What is the accuracy of CMR angiography for detecting CAD?
The diagnostic accuracy of CMR angiography is reduced as compared with CCTA, with reports of a lower accuracy than that of CCTA. Variability in diagnostic accuracy with CMR angiography has been attributed to a lack of uniformity in pulse sequences and the application of varying analytic CMR have shown comparable abilities to detect CAD as compared with CCTA. A multicenter, controlled clinical trial of patients referred to invasive angiography revealed that magnetic resonance angiography had an 81% negative predictive value for excluding CAD.
