In their recent paper, Dr. Bettencourt and colleagues (1) report similar accuracy for the detection of coronary artery disease (CAD) between cardiac magnetic resonance (CMR) perfusion and an integrated computed tomography (CT) perfusion/angiography protocol.
Unfortunately, the authors did not interpret their CMR images in the standard way (2,3), which may limit the applicability of their findings. They state that only areas with ischemia on CMR perfusion imaging were regarded as positive for CAD and that patients with late gadolinium enhancement (LGE) scar but no additional ischemia were classified as negative for CAD. Thus, patients with infarction and an occluded or severely stenotic supplying vessel would be incorrectly classified as having no CAD by their CMR protocol. For this reason, areas of LGE in an infarct pattern are typically interpreted as demonstrating the presence of CAD (2,3). Because ∼16% of the patients in this study had LGE in an infarct pattern, it would be useful to know the diagnostic performance of CMR if standard interpretation of LGE were used.
