CMR is the gold standard for assessing biventricular size and function. bSSFP Seg Cine is a standard cine method, but requires breath-holding which prolongs table time and limits utility in dyspneic patients. A novel real-time technique RTCSCineMoCo combines free-breathing acquisition with compressed sensing and motion correction. In 100 subjects RTCSCineMoCo generated similar results to Seg Cine for LVEF, LV end-diastolic mass, and RVESV with agreement including no difference at Bland-Altman analysis for all LV and RV measures. The shorter table time for RTCSCineMoCo and ability to robustly image dyspneic patients are important enhancements for clinical practice.
