Is It Deep Vein Thrombosis (DVT) or Pulmonary Embolism?

A pulmonary embolism occurs when a blood clot moves through the bloodstream and becomes lodged in a blood vessel in the lungs. Similarly, in a condition called deep vein thrombosis, clots form in the deep veins of the body, usually in the legs. A blood clot that breaks free and travels through a blood vessel is called an embolism. In either case, you’ll need medical treatment right away to prevent a blood clot from blocking blood flow to your lungs or your heart.

According to the CDC, between 60,000 and 100,000 Americans die every year from deep vein thrombosis or pulmonary embolism and as many as 900,000 people could be affected.

Sometimes these conditions are present with no symptoms at all. Otherwise, symptoms may include swelling, pain, and tenderness, often in the legs. Risk factors include hormone therapy, pregnancy, and extended periods of immobility such as a long car or plane trip.

Symptoms of Deep Vein Thrombosis or Pulmonary Embolism

Call your doctor right away if you have these DVT symptoms, especially if they appear suddenly:

  • Swelling in one or both legs
  • Pain or tenderness in your leg, ankle, foot, or arm. It might feel like a cramp or charley horse that you can’t get rid of. Leg and foot pain might only happen when you stand or walk.
  • Warm skin on your leg
  • Red or discolored skin on your leg
  • Veins that are swollen, red, hard, or tender to the touch that you can see

Symptoms of an urgent condition include:

  • Sudden coughing, which may bring up blood
  • Sharp chest pain or chest tightness
  • Pain in your shoulder, arm, back, or jaw
  • Rapid breathing or shortness of breath
  • Pain when you breathe
  • Severe lightheadedness
  • Fast heartbeat

Tests Your Doctor May Order to Diagnose Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE)

Your doctor will usually begin by obtaining your medical history, as this may provide information about factors that caused the clot. In addition to performing a physical exam, your doctor may order one or more of the following tests:

  • Blood tests, such as D-dimer: This test looks for a protein that shows up in your blood when a clot starts to break down. If you have a clot, levels will be high.
  • Chest x-ray
  • CT Angiography: This non-invasive CT scan uses x-rays and an iodine-containing contrast material to produce pictures of the chest highlighting the blood vessels in the chest and lungs.
  • ECG (electrocardiography)
  • Magnetic resonance imaging (MRI): You’ll lie still on a table while radio waves and a strong magnetic field make detailed pictures of the inside of your body on a computer. (You’ll hear loud tapping or knocking sounds during the test.) You might need to get an injection of contrast material to make your blood vessels show up better. An MRI can find DVT in your pelvis and thigh.
  • Venous ultrasound: This test uses sound waves to confirm the presence of a blood clot. Doppler ultrasound is a special technique that allows the doctor to see and evaluate blood flow through arteries and veins throughout your body. If the results are inconclusive, your doctor may use venography or MR angiography.
  • Venography: This is a special X-ray. The doctor injects a radioactive dye into a vein on the top of your foot to help them see your veins and maybe a clot.
  • V/Q Lung scan: This nuclear medicine exam uses a small amount of radioactive material (called a radiotracer) and a special camera to create pictures that show how blood and air are flowing throughout the lungs.

CT Scans for Diagnosing Pulmonary Embolism

Medical Imaging That Helps Assess Heart Health


Heart disease is the leading cause of death around the world. Contributing factors include a poor diet, lack of exercise, and genetics. Most doctors tell patients that the way to better cardiac health is through medically proven methods of eating better, regular exercise and taking precautions if your family has a history of heart disease.

To detect and combat heart disease, scientists have developed a variety of medical technologies. Medical imaging is a common method for doctors to determine the probability of a patient developing a heart condition. Below is a look at the medical imaging modalities physicians use to assess cardiac health.

CT and CAT Scans for Calcium Scoring

One frequently used medical imaging exam for determining the condition of the heart is through a CT or CAT scan. CT scans use X-rays and computer equipment to produce cross-sectional images of the body, including several types of tissues such as muscles. At Doctors Imaging, we calibrate CT equipment to use the lowest amounts of radiation required for each exam.

A Calcium Scoring screening uses produces imaging of the coronary arteries to determine if they are blocked or narrowed by the buildup of plaque – an indicator for atherosclerosis or coronary artery disease (CAD). The information obtained can help evaluate whether you are at increased risk for heart attack.

A CT scan for coronary calcium is a non-invasive way of obtaining information about the presence, location and extent of calcified plaque in the coronary arteries—the vessels that supply oxygen-containing blood to the heart muscle.

Because calcium is a marker of CAD, the amount of calcium detected on a cardiac CT scan is a helpful prognostic tool. The findings on cardiac CT are expressed as a calcium score. Another name for this test is coronary artery calcium scoring.

A positive test means that CAD is present, regardless of whether or not you are experiencing any symptoms. The amount of calcification—expressed as the calcium score—may help to predict the likelihood of myocardial infarction (heart attack) in the coming years and helps your doctor decide whether you need preventive medicine or adopt diet and exercise changes to lower your risks. The extent of CAD is graded according to your calcium score:

Calcium Score Presence of CAD
0 No evidence of CAD
1-10 Minimal evidence of CAD
11-100 Mild evidence of CAD
101-400 Moderate evidence of CAD
Over 400 Extensive evidence of CAD

Carotid Ultrasounds Can Detect Vascular Problems

If your doctor is concerned about the possibility of a vascular problem leading to heart disease, he or she may order a carotid ultrasound exam. The body has two carotid arteries and if either one becomes compromised, you could go into cardiac arrest or stroke. Ifyou’re worried about your cardiac condition, an ultrasound exam is a safe and effective form of medical imaging. Ultrasound exams simply use sound waves and computer technology to create their images. This allows patients and doctors to see the flow of blood throughout the body in real-time, making it easier to determine the causes of problems and choose treatments.

MRIs Examine Coronary Pathways

MRIs provide another method that doctors sometimes use to test the heart and blood flow through the coronary pathways. MRIs use strong magnetic and radio waves to create images of the internal body.

All these tests are important for gauging your cardiac health. All patients and their symptoms are different. Your doctor will recommend the exam that is right for your needs.

5 Reasons to Get Your MRI or CT Scan at Doctors Imaging

Do you need an MRI, Ultrasound or CT scan? Whenever you do, many doctors’ practices assume you’ll have the test performed in their hospital or affiliated facility. After all, it’s convenient for them. On the other hand, you may have different ideas about what’s convenient, comfortable, and affordable for you.

Here are five reasons to choose Doctors Imaging for your next MRI, CT scan, or X-ray instead of the hospital.

  1. 100% Transparent: Be careful. The staff at your doctor’s office may be under pressure to schedule you at their own hospital imaging department — even if it costs you more. Most hospitals are reluctant to tell you about the total cost of your test. In contrast, the service specialists at Doctors Imaging are friendly, accessible, and transparent about the lower cost of our services.
  2. We can save you money: Many hospitals fail to tell you that you may be charged separate reading fees from their radiologists — another 15% to 25% on top of their high prices. At Doctors Imaging, we have one low fee. Does your insurance plan have a high deductible? If so, ask us about our discounted prices for patients who don’t have insurance or prefer not to use it.
  3. High Quality: Doctors Imaging is committed to advanced imaging technology that is meticulously maintained and frequently updated. Our radiologists are board-certified. Our imaging staff is registered and certified. At the end of the day, we produce medical imaging that is as good or better than the exams produced in a busy hospital. And we think you’ll appreciate our calm office environment; it’s nothing like a hospital.
  4. Insurance: We accept every major insurance including Medicare, Medicaid, and Workers Compensation plans. At Doctor Imaging, you may also enjoy significantly lower costs for the portion of your test not covered by insurance.
  5. Convenience: Unfortunately, it’s not unheard for patients to wait weeks for routine tests at other facilities. But at Doctors Imaging, we provide easy scheduling. We can usually offer you an appointment for the same day or the next day. The hospital staff has to juggle scheduled patients as well as sick and critically ill patients. But at Doctors Imaging, you’ll walk through a quiet waiting room on your way to your exam. We also have plenty of free parking on the first floor, just steps from our front door. You’ll be in and out of our Metairie office before you know it. And we get your exam results to your doctor fast — usually the next day. When your results are ready, you’ll have 24/7 access to our online Patient Portal so you can read your reports and see your pictures for yourself.

Here’s a reminder: It’s OK to talk to your doctor and their staff about skipping the hospital the next time you need a CAT scan, an X-ray, or any other imaging exam. You have the right to choose your imaging facility. You can even choose a different imaging facility after leaving your doctor’s office. It’s true. You can take your written orders wherever you like or simply ask your doctor to send your imaging order to Doctors Imaging.

By choosing Doctors Imaging, you’ll save time and money while you take charge as an active participant in your health care. Call us to start getting the quality, convenience, and service you deserve. You can also request your next appointment online.

What Should Patients Expect During a Low-Dose CT Scan?

CT scans are used by doctors in order to create detailed cross-sectional images of the internal tissues and organs. By using the lowest possible dose of radiation in combination with computer technology, doctors can give patients clear and accurate diagnoses. For those who have never had this particular imaging procedure performed, this preview might help calm your fears or concerns.

What Is a Low-Dose CT Scan?

CT scans are used by doctors in order to create detailed cross-sectional images of the internal tissues and organs.A CT scan uses a combination of X-rays and computer technology in order to create images. X-rays use a small amount of radiation in order to show the body’s internal structures and produce images. On average, Americans are exposed to 3.1 mSv of radiation annually. CT scans use a slightly higher amount than that and qualified radiologists use the lowest possible dosage based on the size of a patient.

What Happens During the Exam?

CT scanners have the appearance of a tube with a spinning detector that collects the images your radiologist will use. For some procedures, the radiologist may ask that you abstain from eating for one or more hours prior to your examination.

Your CT scan will proceed as follows:

  1. While lying on your back,  a table will move your body slowly, feet-first, through the machine.
  2. If needed, your doctor may request contrast  for your CT scan procedure. Contrast is a substance that is used during imaging procedures to better understand your medical condition. Contrast material will be administered through an IV or by drinking a flavored substance.
  3. As you are moved through the machine, your technologist will be able to see, hear and speak to you.

The images and report are created after the procedure is performed, and you and your personal doctor can review the results  together to determine your treatment options. You may feel a warm sensation or a metallic taste after an injection.
You should inform your doctor if you have medication allergies or an allergy to iodine. You should also let your doctor know if you suffer from diabetes or any heart, thyroid or kidney conditions as contrast material may sometimes cause an adverse reaction in patients with these conditions. Otherwise, CT scans are non-invasive and painless and can provide incredibly useful information for your doctors to use in providing the best treatment options for you.

Doctors Imaging is now offering low-dose CT lung cancer screenings, recommended annually for those at high risk for lung cancer, for the low cost of just $99. Lung screening is performed without contrast.  To schedule your appointment, use our online appointment form or call 504-883-8111.

What Happens When My Child Gets Medical Imaging?


When children get sick or injured, it’s up to the parents and physicians to work together to find the best treatment options for the child. If your child requires hospitalization or surgery, then your child’s pediatrician will likely order one of these common medical imaging exams for children. Learn more about the common types of medical imaging, as well as the benefits and risks of each procedure.

All About Common Medical Imaging Exams for Children

Ultrasounds

Ultrasounds are one of the most common and frequently used medical imaging procedures.  Ultrasounds use sound waves and computer technology to see into the internal structures of the body. Because of the lack of radiation used, they are completely safe to perform on children. Women will often have several ultrasounds performed throughout their pregnancy and all are harmless. Ultrasounds can help determine conditions like cardiovascular birth defects, dysfunction in the reproductive organs, injuries after traumatic incidents like falls or car accidents, and possible cancerous masses. This procedure is also completely painless for children so there is no need for sedation or anesthesia.

CT Scan / CAT Scan

A CT Scan or CAT scan is another medical imaging procedure that your doctor may ask to perform. CT scans use a combination of X-ray and computer technology to examine the body and form images for further study. CT scans are commonly performed when doctors need cross-sectional images of the internal organs such as the chest cavity, abdominal areas, or the brain. If your doctor needs to perform a pediatric CT, the child may be asked to not eat for several hours prior to the examination so that the images will not be distorted. Children will also have to remain very still and silent during the scan. A common practice for CT scans is to administer contrast material so certain growths or blockages can be seen better. Contrast material can be given to a child through an IV or by swallowing the solution. If your child has allergies or a kidney condition, you should inform the doctor or technician prior to the scan.

CT scans use small amounts of radiation in order to better highlight the different types of structures in the body. Although the dose is relatively small, repeated CT scans can incur a slightly higher risk of cancer. But the advantages in diagnosis that CT scans can provide far outweigh the potential risk. The best way to limit the exposure is to only have CT scans performed when they are essential and to have the mechanisms narrowed onto one part of the child’s body. Discuss options with your doctor and child.

X-Rays

X-rays are another extremely common medical imaging procedure performed on both adults and children. If your child has a recent injury or needs surgery, doctors will often ask that an X-ray be performed to determine conditions like bone fractures, breaks and growth dysfunctions. X-rays are performed relatively quickly so the time your child spends exposed to the small doses of radiation is limited. Ask your doctor or imaging facility if they use analog X-rays or digital. Digital X-rays use much smaller doses of radioactive material to examine the body.

MRI

MRI or a magnetic resonance imaging exam is an imaging practice that doctors will usually perform if the child has a cardiovascular or brain condition, bleeding problems, childhood cancer or a type of growth disorder. MRIs use no forms of radiation so children are safe to have this procedure performed. MRIs use radio and magnetic waves to excite the atoms within the body and then use computer technology to collect these atoms and form the image of the body. Possible points of discomfort for a child would be remaining still for very long and having contrast material administered.

Having any medical imaging procedure performed can be a scary experience for both parents and children. But it is important to remember that these tests are created to improve the health of children. If you have serious reservations or fears, speak with a doctor or technologist about all of your questions. Your child cannot ask these questions, so it your job to stay informed and calm so they can stay healthy and happy.

Doctors Imaging is prepared for your child’s visit to our calm office environment. Scheduling is simple, and you can either do it online, or by simply calling 504-883-8111.

Should I Get an X-Ray, MRI, or CT Scan for My Injury?

Every patient is different as well as every injury. The way people injure themselves, the condition of the affected area prior to the injury, as well as the patient’s response to injury, are all factors in assessing the damage as well as creating a plan for the restoration of the area. If you have obtained an injury you feel you can’t care for on your own, you should speak to your doctor about scheduling a procedure that will be best able to determine the extent of the damage and after you and your physician can discuss plans to heal and avoid further injury. Here is a list of common medical procedures that your doctor may schedule for you in order to determine the degree of injury.

An X-Ray


An X-Ray is usually the first procedure a doctor will schedule for an injury, particularly sports-related injuries. X-rays are some of the oldest and most used forms of medical imaging. X-rays are common procedures for joint and bone fractures and breaks. X-rays are also used for examining arthritic joints and determining the location and condition of cancer cells in the bones. X-ray procedures are totally painless and just require the patient to lay very still for the length of the imaging as the slightest involuntary movement can distort the image and the procedure will have to be restarted. Getting an X-ray will be the fastest way to determine if there has been a bone break, dislocation or fracture.

An MRI Scan

Your doctor may also order an MRI scan if the injury cannot be properly determined from an X-ray or if your injury pertains to any of the joint, muscular or skeletal systems of the body. An MRI scan would be particularly helpful if your injury has caused any type of vascular problem such as internal bleeding or clotting or if there is soft tissue damage. MRI scans are useful in determining any overall damage from an injury beyond what an X-ray can relate. MRI scans contain a minute amount of pain from an intravenous injection of contrast material but nothing further. Contrast material will not have a reaction in the body excluding a slightly cool sensation unless the patient has an allergy to iodine.

A CT Scan

Your doctor may also order a CT scan for an injury. Do not be confused if your doctor orders a few tests for you. It does not necessarily indicate an extreme amount of physical damage. Your doctor could just be trying to get the best angles and images in order to make the most thorough diagnosis and by extension the best medical plan for mending your injury. Your doctor may order you a CT scan if he is particularly worried about tissue damage. CT scans using contrast material are able to create cross-sectional images of organs and tissues as well as highlighting which are healthy and which are not. CT scans are relatively painless as well, excluding the pinprick of the IV needle, but in some cases, the contrast material is swallowed to outline the digestive system.

Make the Choice

If you have an injury that cannot be helped by over the counter medications and naturalistic healing methods, you should speak to your doctor about ordering some of these procedures because a serious injury left unattended can become a much more harmful problem. Without proper medical attention and testing, a slight injury can morph into a complex affliction. Even with injuries that feel minimal in pain should be examined by a doctor in order to avoid further complications and injury to the area. The advances in medical technology have provided us with the tools and resources to make better choices concerning patient experience and healing.

What is the difference between a CT and a PET-CT scan?


CT and PET-CT scans are very common procedures that doctors administer every day to help localize their examination and to provide the most thorough diagnosis. Both procedures contain varying, minimal risks but can provide huge benefits for patients that need a more in-depth examination and specialized treatment.

What is a CT scan?

A CT scan or a Computed Tomography scan is a medical procedure that uses x-ray radiation and fascinating computer technology to create cross-sectional images of the body’s organs and tissues. CT scans can also be called CAT or Computed Axial Tomography. CT scans take helical images of the examined part of the body which produces better 3-dimensional imaging. The better the image, the better the diagnosis your doctor can make. CT scans are particularly useful in the examination of tissues, cancer staging, and determining vascular disease.

What is a PET-CT scan?

A PET-CT scan or Positron Emission Tomography is a medical procedure similar to a CT scan but PET-CT scans are commonly used in determining the difference between healthy and diseased tissue. Using nuclear medicine these exams allow particular focus on oncological symptoms in the brain and heart as well as any vascular or tissue abnormalities.

What are the procedures like?

The biggest difference between a CT and a PET-CT scan is the machinations of the procedure. There are varying states of discomfort between both procedures, but both are relatively painless and easy to complete for any patient.

A CT machine looks like a large tire with the patient placed inside the “hole.” The patient is placed on the examination table and will be administered contrast material through the mouth or intravenously. The feet will be the first to enter into the machine and the body will be slowly moved into the chamber. The procedure lasts approximately 10-30 minutes. Patients typically report that they hear a slight whirring sound which is the machine rotating around them gathering imaging. The doctor will able to speak to you and you will be able to respond.

A PET-CT scan is similar to a CT scan in some ways but the biggest difference between the two is the instructions prior to the exam. Most doctors and facilities will request that a patient not eat at least 4 hours prior to the scan and to drink lots of water. The exam also lasts slightly longer at about 30-45 minutes. Contrast material is commonly used as well and will either be  administered through an IV or by inhalation. If the PET-CT scan is being administered because of possible heart disease, the patient will often be asked to perform a stress test. The body will be examined at rest and during exercise in efforts to determine any cardiovascular problems. You may also hear a buzzing or clicking sound during this procedure.

Which procedure is more painful?

Both procedures have a minimal amount of pain and discomfort. The most common complaint is concerning the IV injection site or a claustrophobic feeling. But the contrast material is necessary for properly determining the condition of tissues and veins as well as highlighting possible cancerous cells. Furthermore, the body moves through the machine. It only covers the area that will be examined — it does not encapsulate the entire body.

Are there any risks?

Doctors and imaging facilities have been able to minimize the risks surrounding these procedures to practically nothing. Both a CT and PET-CT scan use small amounts of radiation to image the examined area. If you are pregnant or could possibly be pregnant, you should let your doctor know. There is no medical evidence that the amount of radiation is dangerous for an unborn child. But if there is another safer method to examine, your doctor can help you understand your options. Also if you have any implanted devices, artificial body parts or features such as hearing aids or dentures, talk to your doctor about what needs to removed for the procedure.

The History of Medical Imaging

The first X-RayMedical imaging is a form of technology that has revolutionized the medical field in the past century.  With these new innovations, doctors were able to elevate the standard of practice and the experience of the patient. Now, areas of pain or trouble can be non-invasively examined and treatment can begin without the patient even needing to go under. But when did the innovation of medical imaging begin?

Read below to take a trip down memory lane and find out how the medical field and the technology industry have been working together to build a better, healthier world.

Röntgen performs X-Ray in 1895

Professor Wilhelm Röntgen accidentally discovers the ability to look through the skin and see the bones of the body while performing experiments on another project. While working with a cathode ray generator, he noticed an image that was left when the cathode rays came into contact with the vacuum tube. He performed the first X-ray on his wife’s hand and even gave the technology the name we use today, calling this discovery “X” rays because they were unsure what exactly they were. This invention was eventually standardized by William Coolidge and his X-ray known as the “Coolidge tube” is what all modern X-ray machines are based from.  The first X-rays required at least 11 minutes of exposure to produce a quality image. Now X-rays take only a few seconds and they use about 2% of the radiation amount seen in the early 20th century machines.

Scientists Use Ultrasounds in the 1960s

The basics of sonar had been discovered and utilized during World War II as a form of maritime warfare. In the early 1960s, scientists discovered that sending sound waves into the body would bounce off the internal structures and then returned to the ultrasound machine to be reformatted into images for doctors to see. This allowed doctors to non-invasively search for tumors and other growths.

Damadian Discovers MRI in 1970

Dr. Raymond Damadian discovers that different animal tissues emit different signals, as well as that cancerous tissues, take much longer to return the signal sent through them. This is the basis for magnetic resonance imaging. In 1977, Dr. Damadian created the first full-body MRI machine which he named the “Indomitable.”

Hounsfield Invents CT Scans in 1972

The 1970s showed the first instance of computer technology mixing into the medical field with Sir Godfrey Hounsfield’s invention of the CT machine. He theorizes that you could see into an object if you took X-rays from different angles of the object through a machine that would appear as “slices” which could then be put together to form an image. With his idea, he formed the first “axial tomography” machine which we now know as the CT machine. In 1979, he received the Nobel Prize in Medicine and was later knighted by the British Royal Family.

Since then, all of these machines have entered into the digital age and are now updated with the latest technology available. This means that there is less potential risk for patients as well as a greater ability to diagnose and treat.

Car Accident Head Injuries, Safety and Precautions

Car accidents can be some of the scariest moments of one’s life. Despite the innovations and advances in automobile safety technology, human error is still hard to beat. About 20 percent of all reported head injuries are the result of an automobile accidents. Buckling seatbelts is a major preventative measure that everyone should apply when riding in a car. However, car accident head injuries can still come from steering wheel collisions, airbag deployment as well as window, windshield and debris injury.

Head injuries can vary in the degree of seriousness. Some people walk away with a bump on the head often referred to as a contusion, others suffer from conditions like concussions, and some have more traumatic brain injuries such as memory loss. In the event of a car accident, having the proper body and brain imaging can be a major protective measure against the progression of the injury.

At Doctors Imaging, we have lots of experience helping those who have suffered from car accident head injuries. Whether it is our digital X-ray capabilities for broken bones or more advanced exams to determine the extent of brain injury, at Doctors Imaging we are committed to providing high-quality imaging services for the greater New Orleans area.

Our most detailed exam for brain injuries is diffusion tensor imaging (DTI). Because car accident head injuries are so common, we are proud to be offering this service to the Gulf South region because of the numerous benefits it provides. Diffusion tensor imaging is an advanced form of MRI that traces the movement of water and hydrogen atoms in the nerve pathways of the brain.

A DTI exam measures brain injuries that are not seen on MRI and CT scans performed elsewhere.

Conventional MRI scans are the best for determining internal or soft tissue damage in the body. However, CT scans and MRI are not adequate for tracing the nerve pathways in the white matter of the brain and highlighting otherwise unseen brain injuries. DTI goes further than a conventional brain scan. Water molecules follow a certain pattern in the brain along the nerve pathways. When you can see that the path has been disrupted, physicians know to look further into this area to find possible injury. Because head injuries can appear non-threatening, they can develop into more serious conditions in the weeks and months after the accident.

DTI is especially useful for patients who have suffered a concussion. Some concussions can heal in a few days while others can leave more lasting injuries. The only way that diffusion tensor imaging can be performed is with a 3.0 Tesla MRI and special software capabilities. Doctors Imaging is the only facility in the Gulf South. For this reason, we see patients from all over the region who are looking to determine the extent of their sport, work injuries and car accident head injuries.

If you have more questions about head injuries, diffusion tensor imaging or other injuries that require imaging, please contact Doctors Imaging at 504-833-8111 or visit the website of The Concussion Group for more information. If you would like to set up an appointment for imaging, you can use our Request Appointment page any time.

High-Resolution CT Scans Fit for a King and You Too

How CT Scans Produce Cross-Sectional Images

CT scans, or computed tomography, use computer technology along with X-ray capabilities to photograph the internal organs. CT imaging produces cross-sectional images of the organs so that doctors do not just see a flat picture, they see slices of the examined area. With CT scans, doctors can see through, into and around different body parts without the impediment of things like bones and muscles. This allows for a high level of detail and accuracy when looking at a patient’s body and finding the cause of disease.

CTs work to take “slices” of the body’s interior, meaning that if there is a spot or area to be examined, the machine takes several images of the same part but from multiple angles, ensuring that nothing is missed. These images are able to uncover what cannot be seen by the naked eye. And for patients that need CTs, they are the best way to get critical medical information without making any incisions. Because of the low dosage of radiation used in CTs, children and senior citizens can experience the benefits and advantages that CTs offer.

How Historians Used CT Scans to Examine King Richard III

CT scans have been a tool for diagnostic medicine for several decades. As medical technology and research become more advanced, this tool has been found in places other than hospitals, including places like laboratories and history books. By using the power of CT machines, numerous educational institutions are able to use CT technology to decipher and explain the mysteries of the past.

Understanding CT scans is a key skill for historians that specialize in discovering anything that has been dead and buried for centuries. For many archeologists and scholars, CTs can provide answers that no other method of academia can. They can even act as a forensic tool in solving centuries-old mysteries. A recent example of this is from 2012 when British scholars found the skeleton of King Richard III, a man who died over 500 years ago. While the stories and portrayal of King Richard III may be varied and less than perfect, what cannot be denied is how he died, thanks to understanding CT scans.

For many centuries, the skeleton of King Richard III was misplaced, a highly unusual fact for a person of royalty. In 2012, a group of scholars matched a map of the Battle of Bosworth Field and found what they believed to be the King’s skeleton underneath a parking lot in central London. However amazing their discovery might have been, without concrete forensic evidence, there would be no way to prove that this was the skeleton of a former English ruler.

Different accounts of Richard III remark at his physical appearance, most notably, a hunchback. The unearthed skeleton contained a spine curvature. Combined with the location of the skeleton, those who found him were positive that it was the former king. Historians were able to test the DNA of surviving relatives of Richard III to find out more about his appearance and answer the question as to how he died. By understanding CT scans and examining the skull, they were able to determine two specific blows to the head as well as another 11 harmful injuries on the body that likely contributed to his death, historians were able to discover all those facts about a 500-year-old skeleton.
