动脉内注射小剂量的钆喷酸葡胺结合快速破坏梯度回波磁共振（MR）序列，以获得兔主动脉和犬冠状动脉的实时投影血管造影图像。动脉充盈和冲洗，以及静脉和灌注阶段，清楚地显示，证明动脉荧光透视，其中使用的MR技术是可行的。
Intraarterial injections of small doses of gadopentetate dimeglumine were combined with a fast spoiled-gradient-echo magnetic resonance (MR) sequence to obtain real-time projection angiographic images of the rabbit aorta and canine coronary arteries. Arterial filling and washout, as well as venous and perfusion phases, were clearly displayed, demonstrating that arterial fluoroscopy in which an MR technique is used is feasible.
