Currently, a standard short-axis cardiac CINE protocol consists of ~7 breath-holds which is time-consuming, costly and patient-unfriendly. We investigated whether it is feasible to accurately quantify biventricular morphology and function in 3 to 2 breath-holds using a new 72‑channel receive array and (compressed-)SENSE acceleration. To that end, we performed a comparison between a 16 channel local array with a SENSE-factor 2 and the new coil with (compressed‑) SENSE factors of 2, 4 and 6. In all cases, left ventricular ejection fractions were similar with acceptable image quality decline for higher acceleration, facilitating cardiac function assessment in only 2 breath-holds.
