The brain computed tomography is a medical research non-invasive type, intended for diagnostics of a wide range of brain diseases.
CT is the first technique in vivo visualization of various brain structures (in American literature this method is often referred to as "computerized axial tomography"). Computed tomography of the brain is based on carrying out x-ray studies with computer analysis of the results that allows us to perceive the subtle differences in the absorption of the x-ray beam in a different (modified and normal brain tissue. Computer graphics allows to reveal the layered image "slice" of the brain (thickness from 3 to 10 mm).
Procedure tomography of the brain is performed using a specialized x-ray equipment, which produces a series of images, which are further processed with the use of computer equipment and subject to the detailed study on the monitor. For further research, a series of the images easily printed out on the printer.
Tomography of the brain in most cases, expanding the assessment base of the skull and bones of the arch, located in the area of research. Tomography of the skull provides detailed information with extensive injuries, brain tumors, stroke and other brain diseases. Using a CT scan of the skull, you can assess the level of damage to bone and soft tissue injuries of the face area for planning treatment volumes.
The main indications for imaging of the brain:
- long-term severe headaches, occasional dizziness;
- the occurrence of seizures, increased frequency of seizures;
- memory loss, gaps in memory and impaired orientation;
- the rapid deterioration of vision, double vision, sensation of "fog" on the eyes;
- diseases of the brain vascular nature (brain ischemia, stroke);
- suspected cancer, infectious diseases, developmental disorders and brain and its membranes;
In addition, CT scan of the skull is extremely informative in ENT practice, for example, during the study of the causes of hearing loss, modification sinuses.
Tomography of the brain, in most cases, lasts no more than 10 minutes.
The imaging brain is possible after prior consultation with and under the direction of a specialist neurologist or neurosurgeon for detailed specification of the tasks and pick the correct research Protocol.
