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.
