目的 探讨磁共振常规序列与 磁敏感加权成像(SWI)序列对脑微出 血的诊断价值。方法 选择本院2014 年7月至2016年6月收治的80例脑微出 血患者，入院后均行磁共振常规序列 (T1WI、T2WI、FLAIR)及SWI扫描，对 比常规序列及SWI序列的检查结果。 结果 常规序列(T1WI、T2WI、FLAIR) 的脑微出血检出率(8/80)10.00%、 (14/80)17.50%、(45/80)56.25%显著低 于SWI(80/80)100.00%，差异具有统计学 意义(P<0.05)；常规序列(T1WI、T2WI、 FLAIR)的病灶检出率(68/413)16.46%、 (106/413)25.67%、(265/413)64.16%均显 著低于SWI的(413/413)100.00%，差异具 有统计学意义(P<0.05)。结论 脑出血运 用磁共振SWI序列、病灶检出率均高于常 规序列，利于进一步临床治疗的开展，建 议作为磁共振的常规检查序列。

Objective To study the diagnostic value of magnetic resonance conventional sequences compare with the SWI sequence on brain bleeding. Methods From July 2014 to June 2016, 80 cases of cerebral hemorrhage patients were selected in the study in our hospital. After admission, the patients were performed magnetic resonance conventional sequences (T1WI, T2WI and FLAIR) and the SWI sequences scanning. The test results were compared between the conventional sequence and the SWI sequence. Results the detection rate for conventional sequences (T1WI, T2WI and FLAIR) using in cerebral hemorrhage were 10.00% (8/80), 17.50% (14/80) and 56.25% (45/80), which were significantly lower than that of SWI sequence (100.00%, 80/80), with significant difference (P<0.05). The Conventional sequence (T1WI, T2WI and FLAIR) detection rate for lesion were 16.46% (68/413), 25.67% (106/413) and 64.16% (265/413), which were significantly lower than that of SWI sequence (100.00%, 413/413), with significant difference (P<0.05). Conclusion Cerebral hemorrhage detected by using magnetic resonance (NMR) SWI sequence, the detection rate in lesion were higher than the conventional sequence, which was conducive to the further treatment. We Suggest the SWI sequence should as the regular examination in MR sequences.
