磁敏感加权成像对脑微出血与高血压关系的研究

目的:探讨不同分型的脑微出血(cerebral microbleeds,CMBs)与高血压的关系。方法:回顾分析931例行颅脑磁共振检查的患者。其中高血压患者220例,非高血压患者711例。所有病例均加扫磁敏感加权成像序列。结果:Ⅰ型、Ⅱ型、Ⅴ型CMBs在高血压组与非高血压组的检出率差异均有统计学意义(P<0.05~P<0.01),Ⅲ型、Ⅳ型CMBs在高血压组与非高血压组的检出率差异均无统计学意义(P>0.05);高血压组与非高血压组不同分型的CMBs构成比差异无统计学意义(P<0.05)。结论:CMBs多见于高血压患者;Ⅰ型、Ⅱ型、Ⅴ型CMBs多见于高血压患者,Ⅲ型、Ⅳ型CMBs在高血压与非高血压患者的检出率差别不大;高血压患者CMBs以Ⅰ型为主,Ⅴ型次之;非高血压患者Ⅰ型、Ⅱ型CMBs偏多。

Application of SWI in the analysis of the relationship between cerebral micorbleeds and hypertension

Objective:To analyze the relationship between different types of cerebral microbleeds ( CMBs ) and hypertension. Methods:The data of cerebral susceptibility weighted imaging in 931 patients were retrospectively analyzed. Two hundred and twenty cases with hypertension and 711 cases without hypertension were identified. All patients were additionally scanned using susceptibility weighted imaging. Results:The differences of the detection rate of type Ⅰ,Ⅱ and Ⅴ CMBs between the hypertension group and non-hypertension group were statistically significant(P<0. 05~P<0. 01). The differences of the detection rate of type Ⅲ and Ⅳ CMBs between the hypertension group and non-hypertension group were not statistically significant(P > 0. 05). The differences of the constituent ratios of different types of CMBs between the hypertension group and non-hypertension group were not statistically significant (P>0. 05). Conclusions:CMBs is more common in patients with hypertension,typeⅠ,ⅡandⅤCMBs are more common in patients with hypertension, and the differences of the detection rate of type Ⅲ and Ⅳ CMBs between the hypertension group and non-hypertension group is small. TypeⅠCMBs in hypertensive patients is mainly,followed by typeⅤ,and typeⅠand typeⅡCMBs are more in non-hypertensive patients.
