摘　　要：目的 探讨脊髓血管畸形（SVM）病变的磁共振成像技术方法及临床应用价值.方法 回顾分析16例椎管内SVM患者资料,并由DSA检查证实.使用GE Signa 1.5T EXCITE HD磁共振机,GE ADW4.3工作站进行图像后处理,磁共振脉冲序列：矢状面T1WI、T2WI,轴位T2WI及斜冠状面CE-MRA.扫描完后将数据传至工作站,进行图像后处理,观察椎管内SVM的磁共振影像学特征.结果 16例椎管内SVM中,椎管内血管流空现象是椎管内SVM特征性MRI表现,CE-MRA常显示为蚯蚓样或杂乱无章高信号影.结论 MR对诊断椎管内SVM病变安全可靠,可作为首选筛查方法.Objective To evaluate the value and technique of magnetic resonance imaging（MRI） for spinal vascular malformations （SVM}. Methods The data of SVM confirmed by DSA in 16 patients were retrospectively analysed. MR imaging was performed in all cases using GE signa 1. 5T Magneton,the images were processed at GE ADW.4.3 workstation. MRI pulse sequences included sag iuai T3 weighted, coronal TI weighted, axial Te -weighted and coronal conmlst enhanced magnetic resonance imaging （ CE MRA）. MR imaging features of SVM were analysed. Results MR characteristics of SVM in this series were flow void appearances and earthworms or disorder plaques high signal were showed at CE MRA. Conclusion MRi may represent the best modality for the screening of patients suspemed with SVM, it is the first choice of method in diagnosing the disease.
