Abstract: Abdominal MRI suffers from number of limitations such as (1) slow and inefficient acquisition (2) sensitive to motion related artifacts and (3) limited volumetric coverage and spatial resolution which are constrained by the breath-hold capacity of the patients. To overcome these limitations our groups has developed continuous motion robust radial acquisition schemes which when combined with parallel imaging and compressed sensing reconstruction (called GRASP) permits free-breathing simultaneous high spatiotemporal resolution T1 weighted multi-phase dynamic contrast enhanced imaging. Furthermore, ability to extract motion information from such a free-breathing radial acquisition scheme provides an opportunity to perform motion resolved/ motion sorted dynamic contrast enhanced imaging of the abdomen (called extra-dimensional or XD-GRASP). Our current work focuses on extending this framework to model based Dixon radial imaging such that a single free-breathing 5 minute (or less) acquisition can replace all the necessary T1-weighted sequences needed for routine abdominal MR examination.
