CT of the head is a modern diagnostic method,which combines x-ray equipment and computers. It helps to identify injuries, diseases of the brain and its vessels, as well as various injuries to the skull.
What does the CT scan show? Using this method of examination, you can visualize the skull, additional sinuses of the nose, brain vessels, so it is used in the following cases:
In addition, CT of the brain is performed withthe purpose of confirming acute disorders of the circulation of the head, which happens with ischemia or stroke, for the detection of thrombi and hemorrhages. This examination is also used to diagnose focal neoplasms and malformation of the skull, to detect inflammation in the paranasal sinuses, as well as to assess aneurysms and to perform targeted biopsies.
CT of the brain can be performed withthe use of special contrast agents, so it is not recommended for use with a tendency to allergic reactions, especially with increased sensitivity to iodine-containing drugs. Also, computed tomography is not performed with elevated serum creatinine levels, severe bronchial asthma, or with hypothyroidism.
Pregnant women are recommended alternativemethods of examination, since there is a risk of exposure to the fetus. Small children also have a higher sensitivity to radiation, so they spend CT of the brain only on strict indications. It is worth noting that x-ray irradiation increases the risk of cancer, so unjustified computer tomography is unacceptable.
In addition, very obese patients may notfit in the opening of the tomograph or their weight can become an obstacle to the movement of a special table, on which the patient should be placed during the examination.
An important drawback of CT of the brain is that it is impossible to detect the inflammatory process in the meninges with the help of it.
Computed tomography is performed absolutelypainless. It is a non-invasive and highly accurate method of examination, allows simultaneous reception of images of bones, tissues and blood vessels. Unlike X-ray studies, CT provides very clear and detailed images.
In addition, computed tomography allowsdoctors get pictures of internal structures in real time, conduct a targeted biopsy, and, if necessary, separate minimally invasive procedures. The advantage is also that this survey in most cases does not require special training. It is also less sensitive to patient movements (as opposed to MRI) and does not require a delay in breathing.
