摘要
目的探讨多发性硬化(MS)疾病的临床及核磁共振(MRI)信号特点。方法对50例MS患者的部位、范围、病变处形态、MRI信号及强化程度进行回顾性分析。结果MS的特征性表现为同时累及多个不同的部位的斑片状T1WI低或等信号,T2WI高信号影,增强扫描后活动期病变明显强化,静止期病变无强化或强化减弱。结论MRI定位准确,不仅有助于MS的诊断及鉴别诊断,而且是目前MS最敏感的影像学检查手段。它为临床诊断及治疗、疗效评价提供了重要信息。
ObjeCtive To investigate the clinical and imaging characteristics of multiple sclerosis（MS）. Methods MRI findings in 50 cases with MS, including the location, extent and shape of the lesions, as well as the signal and enhancement of the lesions, were analyzed retrospectively. Results The characteristic value performance of MS is ：Simultaneously implicates many different locations, the signal were manifested as patches in shape with high signal change on T2WI and low -or iso -signal on T1 WI ;after enhancement scanning active stage lesions present obvious enhancement effect, repose period lesions present the non - enhancement effect or the enhancement effect are weaken. Conclusion MRI locates accurately, not only is helpful to the MS diagnosis and the distinction diagnosis moreover is the present MS most sensitive mescal imaging inspection method. It for the clinical diagnosis and the treatment, the curative effect appraisal has provided the important information.
