Abstract:
Objective To study MRI feature in the lession and brain atrophy of cerebral multiple sclerosis (MS), and to analyze the relationship and the its correlated factors between cerebral MS and brain atrophy. Methods The MRI data from 80 patients with cerebral MS were collected and these patients were divided into two groups according to age. Each patient received T1-weighted and T2-weighted scanning. The number of lesion, characteristics of lesion and brain atrophy were evaluated and compared with control group. The correlated factors of brain atrophy were analyzed. Results (1)The most focal demyelinating lesions of cerebral MS were orbicular-ovate or similar round like with distinct boundary. Typical lesions presented with equal or long T1 and long T2 signals. The macroaxis of lesion was vertical to tangent line of lateral cerebral ventricle. (2)Compared with control group, the cerebroventricular anfractuosity was longer and lateral fissure was wider on MRI in cerebral MS group. The diameter of brain parenchyma was shorter. Statistic differences were found between two groups. (3)Among correlated factors, EDSS was the main predictive factor for cerebral atrophy. Conclusions The most lesions of cerebral MS are mainly located around lateral cerebral ventricles, orbicular-ovate or similar round like with distinct boundary, equal or slight long T1 and T2 signals on MRI.Brain atrophy is generally in cerebral MS and progress gradually, it is related to the course of disease, the number of lesion, the diameter of lesion and EDSS score. Measurement of brain atrophy may regard as an index about progression of MS.
