摘　　要：目的评价磁共振血管成像(MRA)与数字减影血管造影(DSA)在显示外伤性颈内动脉海绵窦瘘(TC-CF)瘘口中的价值。资料与方法回顾性分析11例TCCF患者的DSA及MRA影像学表现。结果 11例患者中,DSA能明确显示颈内动脉海绵窦瘘(CCF)瘘口者8例(8/11);11例(11/11)患者在MRA及其原始图像上均可直观明确显示瘘口。结论 MRA薄层无间隔扫描的原始图像及可多角度、多方位旋转观察的最大信号强度投影(MIP)图像可明确显示瘘口,优于DSA检查。Objective To evaluate the value of MRA and DSA in displaying traumatic carotid-cavernous fistula.Materials and Methods DSA and MRA imaging appearances of 11 traumatic carotid cavernous fistula were retrospective analyzed.Results All of 11 traumatic carotid-cavernous fistula were demonstrated by MRA and original images（11/11）,whereas only 8 fistula were clearly revealed by DSA（8/11）.Conclusion MRA acquired by thin slice without interval,as well as multi-angle,multi-dimensional rotation MIP images could specifically display the fistula of traumatic carotid-cavernous fistula,and superior to DSA.
