Previous contrast-enhanced whole-heart coronary MRA(CMRA) studies at 3.0T have shown high sensitivity and moderate specificity for the detection of stenosis in patients suspected of coronary artery disease (CAD). However, a major advantage of 3.0T contrast-enhanced CMRA is the potential to combine lumenographic information and associated myocardial viability in the same setting. The feasibility of integrating high spatial-resolution, 3D whole-heart viability imaging and coronary MRA at 3 Tesla has been evaluated in volunteer studies. No clinical results using this technique at 3T were available so far.
