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.
