摘要 目的探讨磁敏感加权成像(SWI)序列对脑海绵状血管瘤诊断的敏感性,定量评价SWI序列较常规MRI序列及弥散加权成像(DWI)序列对脑海绵状血管瘤的诊断价值。方法回顾分析经临床及病理证实的27例脑海绵状血管瘤患者磁共振影像,对T1WI、T2WI、DWI及SWI序列在病灶检出数目、病灶面积方面进行测量。结果 T1WI检出病灶共31个,T2WI检出病灶35个,DWI检出病灶46个,SWI检出病灶106个。单个病灶最大面积:T1WI平均(0.80±0.38)cm2,T2WI平均(0.96±0.43)cm2,DWI平均(1.14±0.56)cm2,SWI平均(1.43±0.61)cm2。结果显示:SWI较T1WI、T2WI、DWI序列病灶检出数目多。在病灶面积显示方面,SWI序列明显优于T1WI、T2WI、DWI序列,且存在显著差异,P均<0.05。结论SWI序列在检出脑海绵状血管瘤的病灶范围和数目方面明显优于T1WI、T2WI、DWI序列,具有重要临床应用价值。
