Whole heart coronary MRA at 3T was acquired in 52 patients with suspected CAD as apart of comprehensive CMR study. After acquiring perfusion MRI and late gadolinium enhanced MRI, navigator-echo gated, 3D-TFE images were obtained with a patient-specific narrow acquisition window (57.9ms}26.8). Acquisition of MRA was successfully completed in all 52 patients, with averaged imaging time of 11.4 } 4.5 minutes. On a vessel based analysis, the sensitivity, specificity and NPV were 88%, 97% and 97%, respectively. 3.0 T coronary MRA performed as a part of comprehensive cardiac MR study is useful for ruling out significant CAD.
