摘　　要：目的分析磁敏感成像技术（T2 Star Weighted Angiography，SWAN）在脑血管畸形的应用优势及脑血管畸形的SWAN影像特征。材料与方法17例疑有脑血管畸形患者，分别应用常规MR扫描和SWAN序列扫描。其中，常规MR序列包括SE T1WI、T2WI、T2FLAIR、DWI。将所得SWAN数据进行最小信号强度投影法图像重建。结果17例患者均获得了清晰的畸形血管图像，其中动静脉畸形7例、静脉畸形3例、海绵状血管瘤5例、毛细血管扩张1例、脑颜面血管瘤综合征1例。结论SWAN对脑内血管畸形诊断较敏感．较其他序列提供更多诊断信息。Objective To discuss the clinical application of T2 Star Weighted Angiography （SWAN） in cerebral vascular malformation and the features of SWAN on MRI. Methods 17 patients who suspected cerebral vascular malformation underwent MR scanning at a 1.5TMR scanner. Both conventional MR technology and SWAN were peffornied. Results 17 cases got good images successfully,including 7 cases of arteriovenous malformation, 3 cases of venous hemangioma,5 cases of cavernoma ,1 case of telangiectasis, 1 case of Sturge-Weber synodrome. Conclusion SWAN is the best sensitive sequence for detecting cerebral vascular malformation, it will provide more complete and detailed information combining with other sequences.
