We present a method for free-breathing whole-heart 3-D CINE imaging based on adaptive triggering and retrospective gating and compare it to a previously published method using prospective triggering. We show that our method is simultaneously robust to heart-rate variability during the scan and able to cover the entire cardiac cycle, which is not the case for prospective triggering. A validation in 6 volunteers shows reduced end-diastolic volume bias compared to a gold-standard 2-D reference for our method. Image reconstruction is integrated into the scanner system and takes less than 3 minutes.
