摘要
目的:回顾分析31例多发性硬化患者的脑MRI常规扫描序列及磁敏感加权成像(susceptibility weighted imaging,SWI)的特征,以提高脑多发性硬化诊断的准确率。方法 :选取2012年8月至2014年6月我院确诊的多发性硬化患者31例,分析所有患者的MRI及SWI检查结果。结果:多发性硬化患者脑脱髓鞘斑块在常规MRI图像上可表现为树冠征、犄角征、煎鸡蛋征和倒逗号征,而在SWI图像上可见有小静脉穿行或绕行病灶。结论:常规MRI及SWI图像上的特异性征象对提高脑多发性硬化的诊断准确率有很高的应用价值。
Objective： To study the features of conventional MR scanning and magnetic susceptibility weighted imaging of brain in patients with multiple sclerosis for improving the diagnostic accuracy. Methods： Thirty-one patients with multiple sclerosis dur/ng Aug 2013 to June 2014 were enrolled. All patients underwent routine MR and SWI examinations. Results： Images of demyelinating plaque on conventional MR were presented as tree crown, horns, fried egg and inverted comma sign. SWI showed small vein through or bypass the lesions on imaging. Conclusions： Specific signs on conventional MR and SWI scanning of brain could improve the accuracy of diagnosis of multiple sclerosis.
