CT SCAN OF THE BRAIN

Computed tomography of the brain is a fast, simple and painless way to determine the smallest negative changes in human brain tissue. During the examination the CT scanner takes many images of the brain, the so-called "slices", on the basis of which the computer forms a three-dimensional model of the brain.

INDICATIONS FOR CT OF THE BRAIN

Most often computed tomography of the brain is prescribed in case of suspicion of a brain attack, the presence of a tumor, the formation of a blood clot, multiple sclerosis or meningitis. Computed tomography with a contrast agent is effective in detecting pathologies of the development of cerebral vessels (arteriovenous malformation).

A brain CT scan may be recommended if the following symptoms are observed:

  • severe headaches;
  • impaired judgment;
  • slurred speech;
  • rapid deterioration of vision;
  • dizziness;
  • deterioration or loss of coordination of movements;
  • epileptic seizures;
  • suspected high intracranial pressure;
  • paralysis;
  • loss of sensitivity of body parts.

 CT can also be prescribed in the case of traumatic brain injuries of various degrees of severity.

PREPARING FOR A BRAIN CT SCAN

Computed tomography of the brain is performed without any preliminary preparation. If it is necessary to use a contrast agent, then the patient is recommended to drink more liquid before the procedure – it helps to speed up the removal of contrast from the body after the examination. A patient should also stop eating and drinking liquids 4 hours before a CT scan examination.

The patient must take off accessories containing metal: jewelry, hairpins, glasses, hearing devices, etc, just before performing a CT scan study.

HOW A CT SCAN OF THE BRAIN IS PERFORMED 

A CT scan does not last more than a few minutes, but you should be prepared to spend about half an hour in the clinic. Most of this time is spent on preparing and forming a conclusion based on the results of the study.

When CT scan of the head is going to be conducted patient lies down on the scanner table, fixing the head in a stationary position. After that, the table with the patient drives into the tunnel of the scanner and the examination begins. At this time the doctor stays in an adjacent room, watching the patient through a special window. Communication between the patient and the diagnostician is carried out with the help of an intercom device which is built in the CT scanner. For several minutes, during which the examination lasts, the patient is required to stay still.

The patient does not experience painful or unpleasant sensations during the study – the impact of the scanner does not affect his well-being in any way.

If the examination is carried out with a contrast agent, its introduction is performed by means of a special automatic injector. In this case there may be a short-term feeling of warmth spreading through the body, or a metallic taste in the mouth, which also quickly passes.

CT with contrast is contraindicated in patients with renal or heart failure, type II diabetes mellitus, or allergies to iodine, shellfish, and contrast media. For all other categories of patients CT is a safe and fast way to get examined.
