MR T2 Weighted sequences on the brain demonstrate disseminated "high signal zones" (HSZ) in patients with Multiple Sclerosis; these morphological alterations are corresponding to the plaques. From the very beginnings of MR in 1981, everybody recognizes the main importance of this fact. MR appears as the most sensible exploration in patients with M.S. But the signal alteration is not specific; the clinical considerations and the evolution are requested. The aim of this work is to give a reference tool for evolutive evaluation of the disease. A work station with a specially developed software are presented. The HSZ thresholding is partially automatic. The edition of a cerebral mapping is developed. These results are discussed.
脑部的磁共振成像（MR）T2加权序列显示，多发性硬化症患者存在散在的“高信号区”（HSZ）；这些形态学改变与斑块相对应。自1981年磁共振成像问世之初，每个人都认识到了这一事实的重要性。磁共振成像似乎是多发性硬化症患者最敏感的检查方法。但信号改变并不具有特异性，还需要结合临床考虑和病情进展情况。这项工作的目的是为该疾病的进展评估提供一个参考工具。本文介绍了一个配备专门开发软件的工作站。高信号区的阈值设定部分是自动的。还开发了脑图谱编辑功能。并对这些结果进行了讨论。
