We have developed a 3DPR based contrast-enhanced coronary MRA technique that delivers good image quality at (1.0 mm) 3 spatial resolution with scan time of 5 minutes. Further investigations are warranted on subjective image quality evaluation, protocol optimization, and tests on patient population with suspected CAD.
