Accelerated 3D-FSE using Compressed Sensing (CS) with a 30% scanning time reduction has been recently introduced and evaluated for knee MR images. 3D-GRASE is a hybrid FSE-EPI sequence that can achieve higher time-efficiency scans, since it acquires more k-space data per refocusing pulse. The purpose of this work is to present CS 3D-GRASE to achieve even faster musculoskeletal MRI acquisitions.
