目的探讨多发性硬化(MS)患者脑与脊髓的MRI特征。方法回顾性分析36例临床确诊MS患者的MRI表现。结果 MS病灶颅内好发部位为侧脑室周围(50.2%),半卵圆中心(24.7%),胼胝体(11.2%),脑干(8.5%),小脑(5.2%)。脊髓为颈胸段,双侧脑室旁病灶为多发大小形态不同的长T1、长T2信号影与侧脑室壁垂直,脊髓病灶为纵行长T1、长T2及等T1、长T2信号影。结论 MS的MRI特点主要为脑和脊髓白质多发大小形态不同病灶。

Objective To investigate the MRI features of brain and spinal cord in patients with multiple sclerosis (MS). Methods The MRI findings of 36 clinically diagnosed MS patients were retrospectively analyzed. Results The incidence of intracerebral cranial lesions in MS lesions was around the lateral ventricle (50.2%), hemisphere (24.7%), corpus callosum (11.2%), brainstem (8.5%) and cerebellum (5.2%). Spinal cord was neck and thoracic segment. The bilateral paraventricular lesions were long T1 and long T2 signs with vertical and lateral ventricular wall. The spinal cord lesions were long T1, long T2 and equal T1 and long T2 signals. Conclusion The main MRI features of MS are multiple lesion of multiple size and shape of white matter in brain and spinal cord.
