Conventional cardiac MRI (CMR) acquisitions in children are limited by long acquisition time, need for sedation, and an inefficient workflow. A conventional cine SSFP short-axis stack typically takes 5-7 minutes to complete and is ineffective for subjects with arrhythmias. Available alternatives like free-breathing, real-time cine (RT-cine) SSFP have suboptimal temporal and spatial resolution. Recent advances in compressed sensing (CS) MRI techniques may overcome this limitation. We hypothesize that a CS-based approach will allow the scan time for a short axis RT-cine stack to be shortened to less than a minute without compromising spatial or temporal resolution. Read More
