Intracranial Arteriovenous Malformations: Real-Time Auto-triggered Elliptic Centric-ordered 3D Gadolinium-enhanced MR Angiography—Initial Assessment

Abstract
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.
