Magnetic resonance imaging (MRI) guidance for coronary in-
terventions offers potential advantages over conventional x-
ray angiography. Advantages include the use of nonionizing
radiation, combined assessment of anatomy and function,
and three-dimensional assessment of the coronary arteries
leading to the myocardium. These advantages have prompted
a series of recent studies in this field. Real-time coronary MR
angiography, with low-dose catheter-directed intraarterial
(IA) infusion of contrast media, has achieved in-plane spatial
resolution as low as 0.8 0.8 mm2
and temporal resolution
as short as 130 msec per image. Catheter-based IA injection
