Introduction:
CT scans (or computed tomography scans) are widely used for a variety of medical purposes, from diagnosing diseases to assessing fractures and other injuries. CT scans can provide detailed imagery of internal parts of the body, and can also be effectively used to create 3D images – allowing doctors to detect and diagnose many serious medical conditions. But, as with any medical procedure, the technology behind CT scans is complex – and many people don’t know much about this powerful medical tool. Here, we take a look at 15 interesting facts about CT scans:
Fact 1: CT Scans Were Originally Developed in 1972
The idea for a CT scan was developed in 1972, by British engineer Godfrey Hounsfield and South African physicist Allan Cormack. They were presented with the Nobel Prize in Physiology or Medicine in 1979 for their work. The machines that they initially designed were large and bulky machines, and took around 30 minutes to produce a single image. However, this technology has since advanced significantly, and modern day CT scanners can produce images within seconds.
Fact 2: CT Scans Use a Combination of X-Ray and Computer Technologies
CT scans use a combination of x-ray and computer technologies in order to construct detailed internal images of the body. When the scan is performed, an x-ray beam is directed around the area of the body being scanned. A computer is then used to convert the x-ray images into digital pictures, which can then be viewed in 3D.
Fact 3: CT Scans Are Non-Invasive
CT scans are a non-invasive medical test, meaning that the patient is not exposed to dangerous radiation or harmful dyes. The only discomfort that a patient may experience during the scan is from lyingstill on the table for an extended period of time.
Fact 4: CT Scans Can Be Used to Detect Cancer
CT scans are an extremely useful tool in detecting and diagnosing cancer. By producing detailed images of the interior of the body, the scan can be used to detect potential tumors in organs and other areas of the body.
Fact 5: CT Scans Have Low Risks
The risks associated with CT scans are relatively low, especially when compared to other medical procedures. As stated earlier, CT scans are non-invasive, and the engines only use small doses of radiation. As such, it is considered a relatively safe procedure.
Fact 6: CT Scan Machines Come in Different Sizes
CT scan machines come in a variety of sizes. The most common machines are the full-body CT scan machines, which are quite big and bulky, and these machines are usually situated in a large room. Some machines, however, are much smaller – such as those designed for babies, which are designed to fit inside of incubators.
Fact 7: CT Scans Are Used to Diagnose Injuries
CT scans can also be used to diagnose and assess a variety of injuries, from fractured and broken bones to head injuries. In such cases, the scan can help doctors to evaluate the extent of the injury and determine the best course of treatment.
Fact 8: CT Scans Can Help Locate Foreign Objects in the Body
CT scans are also used to locate foreign objects in the body, such as bullets or shrapnel. By locating the foreign objects, they can then be safely removed.
Fact 9: CT Scans Can Be Combined with MRI Scans for More Detailed Images
CT scans can be combined with MRI (magnetic resonance imaging) scans in order to produce an even more detailed image. Together, they can provide a level of detail that cannot be achieved with either scan alone.
Fact 10: CT Scans Can Detect Blood Clots in the Body
CT scans can also be used to detect blood clots in the body, which can be extremely dangerous and could lead to a stroke or heart attack if they are not located and treated quickly.
Fact 11: CT Scans Can Follow Pregnancy
CT scans can also be used to follow the progress of pregnancy. By giving detailed images of the baby, it can help in monitoring the baby’s growth and health.
Fact 12: CT Scans Are Used to Monitor Heart Function
CT scans can also be used to monitor the functioning of the heart. By producing detailed pictures of the heart, it can help to detect and diagnose potential problems.
Fact 13: CT Scans Are Used to Find Blocked Blood Vessels
CT scans can be used to locate and diagnose blocked blood vessels, which can be caused by plaque build-up or other issues. By locating the blockages, doctors can begin to treat the issue appropriately.
Fact 14: CT Scans Provide Precise Measurements of Structures in the Body
CT scans possess the ability to provide precise measurements of structures in the body. By providing detailed pictures, it can help to accurately diagnose problems and track changes in certain structures over time.
Fact 15: CT Scans Help with Planning Surgery and Treatments
Using CT scans, surgeons and other medical professionals can plan surgery and treatment procedures with greater accuracy. By providing detailed images, it can help to ensure the surgery or treatment goes as expected.
Conclusion
CT scans are a versatile and powerful medical tool for doctors and medical professionals. By providing detailed images of the body, it can help to diagnose and detect a wide variety of medical conditions and issues. At the same time, it is relatively risk-free for the patient. Overall, CT scans are an essential part of the medical process, and these 15 facts provide a bit of insight into this powerful technology.
