ABSTRACT
Magnetic resonance coronary angiography (MRCA) has been developed to overcome specific anatomic and physiologic properties of the coronary arteries. In the normal adult, the coronary arteries are extremely small (measuring 3-6 mm)1 and tortuous as they descend from the sinuses of Valsalva to the apex of the heart. Imaging of complete coronary arteries requires the acquisition of multiple thin two-dimensional slices (3-5 mm)2-4 or several three-dimensional volume slabs (20-30 mm)5,6.
