What Does tomography Mean
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 makes it possible to obtain tomograms (the images in question).
The word tomography is the result of the sum of three components derived from Greek and Latin, such as these:
-The noun “tomes”, which can be translated as “cut”.
-The verb “graphein”, which is synonymous with “record”.
-The suffix “-ia”, which is equivalent to “quality”.
There are different procedures linked to tomography. Thus, we can differentiate between scans ultrasound , CT MRI and CT scans of X - rays , among others.
Biology, medicine, geophysics and archeology are some of the sciences that use tomography to develop their knowledge. Doctors, to cite one possibility, may order a patient to have a CT scan performed to analyze certain parts of their body.
In this case, the technique involves the use of X-rays to achieve 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 achieve the final image.
CT scans are useful for diagnosing, studying, and treating cancer , for example. They also allow a study of the blood vessels , make the diagnosis of an infection or serve as a guide for a surgeon .
If a person trips and hits their head when they fall, the doctor will likely order a CT scan of the skull . Thanks to these images, you can see if there was any brain damage, bleeding or impact injury. With these data, the professional will be able to suggest a treatment.
However, there are many other modalities of computed tomography that exist, among which are the following:
-The abdomen and pelvis. This usually lasts about half an hour and the patient who is going to perform it will have to previously have what is called contrast. This is a kind of dye, which is usually administered through the veins or orally, with which the aim is to make a more accurate diagnosis of the results of the test itself. You can make the decision to undertake this in order to detect everything from appendicitis to cancer through hernias or kidney stones.
-The thorax. In this case, the contrast, in addition to the two aforementioned forms, can also be introduced into the patient's body through the anal route by means of an enema. In your case, it will be done to find 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 lower spine and the tissues that surround it.
