A standard CMR protocol for the evaluation of cardiac function and myocardial damage in patients with ischemic or non-ischemic heart-disease was compared to a new approach which drastically reduces the scan time. This was achieved by introducing a highly accelerated compressed sensing cine sequence which facilitated significant work-flow optimization. Image quality scores of both methods were equivalent and quantitative results showed good agreement. The mean examination time was reduced from 26:29 ± 5:45 min to 16:15 ± 2:47 min, which corresponds to a 38 % reduction in examination time.
