摘要 目的探讨磁敏感加权成像(SWI)在脑内海绵状血管瘤诊断中的价值。方法对20例海绵状血管瘤进行常规磁共振成像(MRI)扫描及SWI扫描,将SWI图像与常规MRI序列对比分析。由两名放射科医师对MRI常规序列图像及SWI图像进行独立诊断及计数,比较不同序列计数的差异性,并分析两名医师组间的一致性。结果 20例海绵状血管瘤,单发14例,多发6例,SWI检出38个病灶,常规扫描检出25个,SWI发现病灶的敏感性优于常规MRI扫描(P<0.01),且SWI能清晰显示海绵状血管瘤伴发的静脉畸形。结论 SWI对脑内海绵状血管瘤诊断的敏感性高于常规MRI序列,特别是对于小病灶的显示优于常规MRI序列。
