In this study, we have a compared a vendor-optimized compressed sensing (CS) accelerated cine MRI technique with the conventional cine MRI technique. There were no significant differences in image quality and cardiac volumes between the two techniques, except left ventricular end-diastolic volume which was significantly lower with the CS technique. The accelerated technique on average reduced scan time by 50%.
