Due to the different contrast of the identical image, all the details may be appreciated. The pictures show: white matter, cerebral aqueduct, cerebellum, trunk, vascular structures. The tomograph creates images which are presented by means of highlighted and eye shadows. Decryption When decrypting, a particular interpretation protocol can be used. The photographs obtained are weighed against reference MRI data from a proper brain. To accurately decipher the information received, the specialist should thoroughly know the physiological and pathological anatomy. It is obligatory to find out the peculiarities from the operation in the tomograph, that has been useful for the examination. For more details about MRI of the brain check out the best site |
