目的 探讨MRI平扫及增强扫描在 多发性硬化诊断中的应用。方法 回顾性 地分析我院2014年1月-2015年12月期间接 收的33例多发性硬化患者的检查资料，通 过MRI平扫及增强扫描分析多发性硬化病 灶影像特征，并对多发性硬化病灶特点进 行分析，与临床特征进行比对。结果 本 文共33例患者，通过MRI平扫及增强扫描 发现多发性硬化病灶直径3-20mm不等，病 灶多呈不规则团状，共167处，其中17例 患者病灶分布双侧脑室周围，共73处； 13例患者的病灶分布在脑白质深部，共 33处；7例患者的病灶分布在脑干、基底 节区及双侧小脑半球，共21处。其中侧脑 室病灶垂直于侧脑室长轴呈T1低信号，T2 和FLIAIR高信号，病灶边界清晰。增强扫 描可见脑干和侧脑室旁病灶部分强化，部 分不强化。结论 常见的多发性硬化临床 特征多变，主要表现为脑干、神经受损等 症状。随着MRI技术在临床医疗的快速发 展，应关注多发性硬化的诊断与MRI影像 技术相结合，通过总结多发性硬化影像学 的特征来提高MS的诊断准确率。MRI的影 像学资料为MS的诊断提供依据。

Objective Study on MRI scan and the application of enhanced scanning in the diagnosis of Multiple Sclerosis. Methods From January 2014 to December 2015, review analysis the hospital receiving inspection data of 33 patients with multiple sclerosis, through the analysis of the MRI scan and enhanced scan multiple sclerosis lesions imaging characteristics, and analyze the characteristics of multiple sclerosis lesions, and compare the clinical features. Results This article total statistics 33 patients, MRI scan and enhanced scan showed Multiple Sclerosis lesions ranging from 3-20 mm in diameter, lesions irregular group with more than 167, distribution of 17 cases with lateral ventricle around 73;13 cases of patients with multiple sclerosis lesions distribution in deep brain white matter there are 33. Seven cases of lesions brain stem, basal ganglia region, and there are 21 bilateral cerebellar hemisphere. The lateral ventricle lesions perpendicular to the long axis of the lateral ventricle is low T1 signal and T2 and FLIAIR high signal, lesion boundaries clear. Enhanced scanning visible brain stem and lateral ventricle lesions, and part of the lesions were enhanced and parts not. Conclusion Common clinical features of multiple sclerosis and changeful, main show is the brain stem, nerve damage and other symptoms.With the rapid development of MRI techniques in clinical medical, should pay attention to the diagnosis of multiple sclerosis combined with MRI imaging techniques, through summarizing the characteristics of multiple sclerosis imaging to improve the diagnosis accuracy of MS.MRI imaging data provide the basis for the diagnosis of MS.
