目的：探讨磁敏感加权成像(SWI)在颅内微出血(CMB泽)中的诊断价值。方法对50例可疑颅内微出血，进行常规MR头颅平扫快速回波(TSE)，液体抑制反转恢复序列(FLAIR)以及Gd-DTPA增强扫描技术和磁敏感加权(SWI)序列成像检查并结合临床资料进行分析。结果对50例经过临床和手术证实的颅内微出血，SWI序列都有明确的显示，表现为点状，条形，椭圆形的低信号；直径为0.4~6.5 mm；分布在皮层和基底节区。常规TSE序列和液体抑制反转恢复序列(FLAIR)分别检出23例和20例。结论 SWI序列对CMBs的检出敏感性明显高于常规序列，对出血性脑血管疾病的诊断治疗有重要的价值。

Objective To explore the diagnostic value of MR susceptibility weighted imaging (SWI) in the cerebral micro-bleedings(CMBs). Methods Conventional MR sequences including TSE , FLAIR and SWI sequences were per-formed in 50 patients as well as SWI sequence.The numbers of CMB and sensitivity of positive rare on SWI and conventional sequences were compared and statistically analyzed. Results SWI sequences clearly exhibited dot,stripe,round or ring-shaped low signal shadows. With diameter from 0.4 to 6.5 mm. Cerebral microbleeds mainly located in cortex, subcortex and basal ganglia in 50 patients. Compared to 23 cases with spin echo TSE, and 20 cases with FLAIR. Conclusion SWI has predomin flilt advantage over conventional MRI sequences in detecting CMBs. SWI provides an important reference for the treatment and evaluating prognosis of cerebral infarction.
