Cardiac Magnetic Resonance (CMR) perfusion imaging is an emerging noninvasive tool for evaluating coronary artery disease in intermediate risk patients. Its utility may be limited in patients with arrhythmia and gating problems during the scan, which degrade image quality and may preclude accurate interpretation. This study performs an initial evaluation of the quality of images and the diagnostic utility of ungated and self-gated perfusion CMR in evaluating coronary disease in eight patients, including patients with arrhythmia.
