ABSTRACT

A novel method for reconstructing motion-compensated 3D CMRA images from free-running data is proposed. We extend the use of a recent method for non-rigid respiratory motion correction called focused navigation (fNAV) to also encompass cardiac motion compensation that accounts for beat-to-beat heart-rate variability.
Our combined fNAV approach is compared to the previously established cardiac and respiratory motion-resolved 5D imaging in vivo and is shown to provide overall similar image quality and comparable right coronary artery visualizations to 5D imaging in significantly shorter reconstruction times.
