Scar-coronary imaging was obtained using a single navigator-gated 3D fat-suppressed delayed-enhancement MR imaging sequence. Compared to the standard 2D delayed-enhancement imaging, the scar-coronary imaging depicted the myocardial scar sufficiently with good CNR. The patent proximal coronary arteries were visualized well by this imaging. Scar-coronary cardiac MR imaging using a single navigator-gated 3D fat-suppressed delayed-enhancement MR imaging study was feasible for visualization of the myocardial scar and patent proximal coronary arteries.
