MRI with the brain is a technique for examining its structure without interfering with the functioning with the organ. It can be used to examine bloodstream and soft tissues to spot possible injuries and lesions because of strokes.
MRI is entirely safe for humans, you will find practically no contraindications. The only limitations are matched to the availability of pacemakers and metal implants. An engaged magnetic field can heat metals by the body processes or disrupt electronic mechanisms.
Indications for your procedure

Because of the different contrast of the same image, every detail can be appreciated.
The photographs show: white matter, cerebral aqueduct, cerebellum, trunk, vascular structures. The tomograph creates images which are presented available as highlighted and dark areas.
When decrypting, an exclusive interpretation protocol is utilized. The photographs obtained are in comparison with reference MRI data purchased from a normal brain. To accurately decipher the knowledge received, the specialist must thoroughly be aware of physiological and pathological anatomy. It is obligatory to learn the peculiarities with the operation from the tomograph, which has been used for the examination.
