Retrospective adaptive motion correction (AMC) was developed for reducing effects of residual respiration in real‐time navigator‐gated three‐dimensional (3D) coronary magnetic resonance (MR) angiography. In both motion phantom and in vivo experiments, AMC improved image sharpness of coronary arteries. This navigator‐based technique combining adaptive correction and real‐time gating is potentially an efficient and effective motion reduction method for 3D coronary MR angiography. J. Magn. Reson.
