摘　　要：目的:探讨磁共振T1WI、T2WI、T2FLAIR和DWI多序列扫描在多发性腔隙性脑梗死中的应用价值。方法:回顾性分析临床资料齐全的多发性腔隙性脑梗死的MRI表现,共145例(363个病灶)。分析由一位主治医师和一位副主任医师共同阅片并达成一致意见,并与临床分期对照。结果:超急性期43个病灶DWI检出率为100%;T2WI+T2FLAIR检出7个,检出率16%。两者比较有统计学意义(P<0.05)。急性期和亚急性早期共168个病灶,DWI、T2WI+T1WI、T2FLAIR各序列检出率均为100%。亚急性晚期54个病灶,T2WI、T2FLAIR检出率为100%;DWI检出8个,检出率为15%;软化灶98个,T2WI+T1WI、T2FLAIR各序列检出率均为100%;T2FLAIR具有特征性的周边稍高信号环。结论:腔隙性脑梗死应用多序列MRI扫描能准确判断新、老病灶,对新病灶的分期较准确,可指导临床治疗。Objective：To study magnetic resonance T1WI,T2WI,T2FLAIR and DWI multiple sequence scan in the diagnosis of lacunar infarction.Methods：Complete clinical data were retrospectively analyzed in the 145 cases of multiple lacunar infarction and 363 lesions of the MRI performance by a chief physician and an attending doctor who were deputy director of film-reading and reached a common consensus and comparison with clinical staging.Results：In super-acute phase of 43 detection rate of DWI lesions 100%;T2WI ＋ T2FLAIR detected in 7,and the detection rate of 16%;between the two was statistically significant（P0.05）.Acute and early subacute 168 lesions： DWI,T2WI＋T1WI,T2FLAIR detection rate of each sequence was 100%;sub-acute late 54 lesions： T2WI,T2FLAIR detection rate was 100%,DWI detected 8,the detection rate was 15%;malacia 98： T2WI ＋ T1WI,T2FLAIR detection rate of each sequence was 100%;T2FLAIR had a characteristic signal around the ring slightly.Conclusion：Application of multiple sequence MRI scans for lacunar infarction can accurately judge the new and old lesions and new lesions in staging and guide clinical treatment.
