摘要 目的研究磁敏感加权成像(SWI)对脑出血(ICH)诊断价值和对出血灶及微出血灶(CMBs)检出率。方法选取2016年5月至2019年4月我院收治的115例疑似ICH患者为研究对象,分别进行CT和MRI(T1WI、T2WI和SWI)检查,分析CT和MRI各序列对ICH诊断价值和出血灶检出率。结果115例患者确诊为ICH者有89例;CT和SWI诊断灵敏度分别为88.76%和96.63%,特异度分别为88.46%和92.31%,准确率分别为88.70和95.65%,一致性Kappa值分别为0.705和0.877,McNemar检验显示SWI检查和CT检查的准确率比较,差异无统计学意义(P>0.05);89例ICH患者共计182个病灶,其中CMBs有104个(57.14%),CT检出率分别为91.76%和89.42%,T1WI检出率分别为41.76%和20.19%,T2WI检出率分别为45.60%和22.11%,SWI检出率分别为96.15%和97.12%,McNemar检验显示SWI对出血灶和CMBs检出率均明显高于T1WI和T2WI,且对CMBs检出率明显高于CT,差异具有统计学意义(P<0.05)。结论SWI是ICH诊断的有效方法,对出血灶尤其是CMBs检出率较高,其诊断价值比常规MRI和CT具有明显优势。
