Auto-triggered elliptic centric-ordered three-dimensional (3D) gadolinium-enhanced magnetic resonance (MR) angiography was compared with 3D multiple overlapping thin-slab acquisition time-of-flight (TOF) MR angiography in the evaluation of intracranial arteriovenous malformations (AVMs) in 10 patients. Intraarterial digital subtraction angiography (DSA) was the reference standard. Gadolinium-enhanced MR angiograms were found to be equivalent to DSA images in AVM component depiction in 70%--90% of cases and were consistently superior to TOF MR angiograms.
在对10例患者颅内动静脉畸形（AVM）的评估中，将自动触发的椭圆中心排序三维（3D）钆增强磁共振（MR）血管造影与3D多重重叠薄层采集时间飞跃（TOF）MR血管造影进行了比较。动脉内数字减影血管造影（DSA）为参考标准。在70% - 90%的病例中，钆增强MR血管造影在AVM成分描绘方面与DSA图像相当，且始终优于TOF MR血管造影。
