【摘要】目的  探讨磁敏感加权成像(SWI)在高血压伴发脑内微出血(CMBs)中的诊疗价值。方法  入选我院2011年8月至2014年8月收治的44例高血压患者，进行常规及SWI序列扫描，比较各序列对CMBs灶的数目、部位和分布情况，以及高血压水平与CMBs的发生关系。结果  经检查，高血压伴有CMBs的患者比例为50.0%(22/44)，且血压显著高于无CMBs组患者；SWI检测出的CMBs病灶数目682个显著高于T2WI  85个和T2FLAIR  136个，差异具有统计学意义(P＜0.05)；且CMBs在基底节区分布最多31.7%(216/682)，其次为皮层-皮层下，在小脑分布最少。结论  SWI在高血压伴发CMBs中具有明确的诊疗价值。

Objective To investigate the susceptibility weighted imaging (SWI) in hypertension with cerebral microbleeds (CMBs) in the diagnosis and treatmentvalue. Methods 44 patients with essential hypertension were selected in our hospital from 2012 August to 2013 August were, routine and SWI sequencescanning, condition number, location and distribution of CMBs foci compared with various sequences, and the level of blood pressure and the occurrence of CMBs relationship. Results after inspection, the hypertension patients with CMBs ratio of 50.0%(22/44), and blood pressure was significantly higher than that in non CMBs group patients; the number of CMBs lesions were detected by the SWI 682 was significantly higher than that of T2WI 85and T2FLAIR136 with significant difference (P＜0.05); and CMBs in the basal ganglialocated at 31.7%(216/682), followed by cortico subcortical and cerebellardistribution, at least. Conclusion SWI has the value of diagnosis and treatmentin hypertension with clear CMBs.
