摘要
目的探讨磁敏感加权成像(SWI)对颅内海绵状血管瘤(CA)合并静脉血管瘤(VA)的诊断价值。资料与方法回顾性分析17例颅内CA合并VA患者的SWI表现,并与常规MRI(共15例)及DWI(共13例)进行对照。结果 15例患者中,SWI检出CA病灶数33个,VA的引流静脉20条,常规MRI检出CA20个,引流静脉10条;13例同时行DWI扫描的患者,SWI检出CA29个,引流静脉16条,常规MRI检出CA18个,引流静脉8条,DWI检出CA22个,引流静脉11条。结论 SWI对颅内海绵状血管瘤合并静脉血管瘤的诊断具有重要的临床应用价值。
Objective To investigate the diagnostic value of susceptibility weighted imaging in cavernous angioma（CA）associated with venous angioma（VA）. Materials and Methods The SWl darts of 17 patients of CA associated with VA were analysed retrospectively, which were compared to conventional magnetic resonance imaging （ 15 patients） and diffu- sion weighted imaging （13 patients）. Results In 15 cases,33 carvenous angioma lesions and 20 drain veins of VA were detected by SWI, 20 carvenous angioma lesions and 10 drain veins were detected on conventional MR sequences. 13 cases underwent DWI sinaultaneously, 29 carvenous angioma lesions and 16 drain veins were detected by SWl, 18 carvcnous angioma lesions and 8 drain veins were detected on conventional MR sequences, 22 carvcnous angioma lesions and I 1 drain veins were detected by DWI. Conclusion SWI has important clinical value for diagnosing the CA associated with VA.
