The scan resolution of abdominal MR imaging using Cartesian sampling is generally limited by the breath-holding capability of the patient, as the respiratory motion would introduce ghosting artefacts. Here we show that golden-angle stack-of-stars sampling in combination with retrospective motion state binning and elastic registration enables sub millimeter in-plane scan resolutions. The technique allows the patient to breathe freely during the examination, hence improving the patient’s comfort, and simultaneously increasing the achievable scan resolution.
