The use of computed tomography in the diagnosis of brain tumors
Computed tomography (CT) - a modern method of X-ray studies of organs and tissues, which allows you to explore them in layers, with all the information is processed on a computer.
The principle of CT is the following. The patient is placed in a special chamber at the same time he introduced into it gradually, on a special table. At this time, moving around the device, which emits X-ray beam. Here is an image from different angles. All this information is then processed by the computer, after which the patient is shifted back in the chamber for a certain small distance. As a result, we have a cross-sectional images of an organ, and may know exactly what its size, depth and relationship to adjacent organs and tissues.
Why a CT?
CT scan is carried out not only for diagnosis of brain tumors. This method found its application in the diagnosis of various organs and various diseases. It is mainly used for detecting space-occupying lesions, hemorrhages, cysts, trauma, etc. It also allows you to identify osteoporosis, the bone tissue.
Sometimes during the CT scan in the space around the spinal cord may be administered contrast material that reaches the brain. This technique allows you to clearly identify the different structures of the brain.
By itself, the procedure is painless computed tomography.
Risk from Computed Tomography
Computed tomography - a completely safe method. The most common problem may be a reaction to the contrast agent, which is sometimes used. As already mentioned, the contrast agent is introduced, for example, in the vein to the one on the CT scan or other body stood out more clearly. The dose of X-rays, which the patient receives a CT scan is minimal. It causes no side effects.
Note also that the CT is not recommended for pregnant women.
Preparation for Computed Tomography
Before the CT scan, the patient should remove all metal objects. Then he goes on a special movable table. Once the doctor will set up the machine and install the sensor over a patient, a table will move slowly, thus obtained cross-sectional slices.
