Cardiac Motion of Coronary Arteries: Variability in the Rest Period and Implications for Coronary MR Angiography

Abstract

The rest period for coronary arteries in the cardiac cycle varies substantially from patient to patient, which may cause quality to be inconsistent in current coronary MR angiography. A cardiac motion image prior to coronary data acquisition (preimage) may be used to estimate the optimal duration and timing in the cardiac cycle for coronary MR angiography.
