目的：：探讨磁共振磁敏感加权( susceptibility weightde imaging，SWI)技术在高血压患者脑微出血( cerebral microbleeds，CMBs)的诊断价值。方法：回顾性分析南方医科大学第五附属医院收治的62例高血压患者的CT和磁共振检查资料，磁共振包括T1WI、T2WI、T2￣FLAIR、DWI、SWI序列，比较不同序列对CMBs检出率的差异以及CMBs发生部位的特点；同时按临床危险分级分为低危、中危、高危和极高危四组，分析高血压患者脑内微出血与临床危险分组的关系。结果：CT未发现微出血灶，T2WI及T2FLAIR检出CMBs 10例，SWI共发现CMBs有42例，CMBs总数为149个。在各部位的分布按数目依次为基底节区、皮质及皮质下、脑干、小脑。低危组、中危组、高危组与极高危组微出血的阳性率、出血灶数目均有显著性差异( P值<0.05)。结论：SWI在诊断CMBs的检出例数及病灶数上都显著优于常规序列，基底节区为CMBs的好发部位。高血压患者危险分级越高，脑内微出血的机率越高。
目的：：探討磁共振磁敏感加權( susceptibility weightde imaging，SWI)技術在高血壓患者腦微齣血( cerebral microbleeds，CMBs)的診斷價值。方法：迴顧性分析南方醫科大學第五附屬醫院收治的62例高血壓患者的CT和磁共振檢查資料，磁共振包括T1WI、T2WI、T2￣FLAIR、DWI、SWI序列，比較不同序列對CMBs檢齣率的差異以及CMBs髮生部位的特點；同時按臨床危險分級分為低危、中危、高危和極高危四組，分析高血壓患者腦內微齣血與臨床危險分組的關繫。結果：CT未髮現微齣血竈，T2WI及T2FLAIR檢齣CMBs 10例，SWI共髮現CMBs有42例，CMBs總數為149箇。在各部位的分佈按數目依次為基底節區、皮質及皮質下、腦榦、小腦。低危組、中危組、高危組與極高危組微齣血的暘性率、齣血竈數目均有顯著性差異( P值<0.05)。結論：SWI在診斷CMBs的檢齣例數及病竈數上都顯著優于常規序列，基底節區為CMBs的好髮部位。高血壓患者危險分級越高，腦內微齣血的機率越高。

Objective:To investigate the diagnostic value of susceptibility weighted imaging ( SWI ) technique in hypertensive patients with cerebral microbleeds ( CMBs ) . Methods:The clinical data of CT and magnetic resonance imaging ( MRI) in 62 hypertensive patients of our hospital were retrospectively analyzed. And the MRI included T1WI, T2WI, T2￣FLAIR, DWI and SWI sequences, which were compared on the differences in CMBs detection rates and the characteristics of CMBs occurrence sites. Meanwhile, all patients were divided into four groups of low risk, medium risk, high risk and extremely high risk based on the clinical risk classification. And the relationship between CMBs in hypertensive patients and clinical risk classification was analyzed.Results:No CMBs were found by CT scan while 10 cases with CMBs were detected by showed noT2WI and T2￣FLAIR, 42 were found by SWI. And atotal of 149 CMBs were found. The sites of distribution based on the number were as follows:basal ganglia, cortex and subcortex, brainstem and cerebellum. There were significant differences in the positive rate of CMBs and the number of CMBs lesions among low risk group, medium risk group, high risk and extremely high risk group ( P<0. 05 ) . Conclusion:SWI is significantly superior to the conventional sequence in diagnosing the number of detected cases and lesions of CMBs. And CMBs favor to occur in the basal ganglia. The higher the risk classification in patients with hypertension is, the higher the occurrence in CMBs becomes.
