Motility assessment of the small bowel using dynamic MRI can only be acquired with either a limited coverage of the intestines or relatively low temporal resolution, which obscures details of motion during contraction and relaxation. Compressed sensing and parallel imaging (CS-PI) techniques allow higher temporal resolution imaging by acquiring and reconstructing undersampled acquisitions. In this abstract we show that by using CS-PI, accelerations up to 7X could be achieved, which outperforms conventional approaches based on parallel imaging only. As a consequence, CS-PI provides a valuable tool for improved assessment of small bowel motility.
