Called positron, a technique that records images of different planes or sections of the body. The technique involves the use of a device called a tomograph, which allows to obtain tomograms (the images in question).
The word tomography is the result of the sum of three components that derive from Greek and Latin, like these:
-The noun “tomos”, which can be translated as “to cut”.
-The verb “graphein”, which is synonymous with “register”.
-The suffix “-ia”, which is equivalent to “quality”. There are different procedures linked to tomography. Thus, we can differentiate between ultrasound examinations, magnetic resonance computed tomography and X-ray computed tomography, among others.
Biology, medicine, geophysics and archeology are some of the sciences that use tomography to develop their knowledge. Doctors, to name one possibility, may order a patient to have a CT scan to analyze certain parts of her body. In this case, the technique consists of the use of X-rays to obtain a series of images. Different sensors are responsible for sending the signals and then the tomogram is formed through tomographic reconstruction, which involves the use of certain algorithms to obtain the final image. CT scans are useful for diagnosing, studying and treating cancer, for example. They also allow the study of blood vessels, diagnose an infection or serve as a guide to the surgeon. If a person trips and hits their head as they fall, the doctor will likely order a CT scan of the skull. Thanks to these images you can see if there has been any brain damage, bleeding or impact injury. With these data, the professional will be able to suggest a treatment. However, there are many other CT modalities, including the following:
-Abdomen and pelvis. This usually lasts about half an hour and the patient who is going to do it must have previously had what is called a contrast medium. It is a type of dye, generally administered intravenously or orally, with which it is intended to make a more accurate diagnosis of the result of the examination itself. The decision to do this may be made to detect everything from appendicitis to cancer to hernias to kidney stones.
-The chest. In this case, the contrast, in addition to the two routes mentioned above, can also be introduced into the patient’s body anally through an enema. In your case, it will be done to locate injuries, infections, tumor masses, bleeding or inflammation in certain areas of the chest.
-The lumbosacral spine, which is the one that tries to know the real state of the lumbar spine and the tissues that surround it.
