Imaging of the brain

 Magnetic resonance imaging of the brain
 Imaging of the brain - an indispensable way to diagnose the structural changes occurring in the brain and blood vessels.

There are various methods of brain imaging, characterized the results and have different effects on the human body.

Computed tomography of the brain

Computed tomography allows a stratified analysis of the brain: consider it in numerous sections in a couple of millimeters.

Imaging of the brain by irradiation

Brain imaging can be performed with the help of X-rays - the patient's head X-rayed. The output is a black and white image in which the visible tumor effects of trauma, stroke and other pathological processes. The method is considered to be quite informative, but unsafe due to the fact that the patient has to be subject to significant radiation.

Magnetic resonance imaging of cerebral vessels

Difficult, but very accurate method of diagnosis is considered magnetic resonance imaging of cerebral vessels. To obtain an image effect using the magnetic resonance of hydrogen atoms. With this imaging of the brain can detect multiple sclerosis, inflammatory and cardiovascular disorders, to produce thin sections of brain and examining the various areas of blood supply to the three-dimensional image. Tomography cerebrovascular pathology reveals circulation in the early stages. This method is considered safe, it can be used to carry out imaging of the brain and the child. Only in this case, during the examination of infants, they were anesthetized, they fed two hours prior to imaging.

 Computed tomography of the brain
 Imaging of the brain-child of pre-school age, it is desirable to assign in the morning. The day before the procedure is recommended to put the baby to bed later than usual - so that he was sleepy and, accordingly, sedentary and calm during the examination.

Spend tomography brain child under the supervision of a physician and anesthesiologist (if performed anesthesia).

The only contraindication to the use of the method is to use a patient's pacemaker - the magnetic field has a negative impact on their work. Assign similar brain imaging at the patient's complaints about noise in the ears, dizziness, frequent headaches, with vertebrobasilar insufficiency, vegetative-vascular dystonia, vascular ischemia of the brain after a stroke.

Positron Emission Tomography

The smallest details can be considered the brain using positron emission tomography (PET), based on the use of radiopharmaceuticals - specifically labeled with radionuclides chemicals.

The result of the survey is a color image, which you can see available and vary in color from healthy areas of pathology and know their exact location. This method is effective in imaging the brain suspected vascular abnormalities and inflammation in the brain, it can show even small tumors (1 cm), do not cause clinical manifestations. Using PET set ischemic disorders, Alzheimer's disease, epilepsy, learn about the consequences of injuries.

From other species Tomography PET is characterized in that it is applied not to study the anatomy of organs and tissues and to assess their functionality. For example, if the CT scan shows the localization of the tumor in the brain, the PET allows to evaluate its growth. Quite often, these two methods are combined for advanced imaging analysis of the patient's condition.

It is impossible to carry out positron emission tomography pregnant and lactating women, as well as patients in serious condition - due to the need for a long time to keep stillness.
