Recent work using Compressed Sensing (CS) reconstruction shows promising in greatly reducing diffusion spectrum imaging (DSI) scan time without jeopardizing critical image information. We evaluate the performance of several CS algorithms on simulated fiber data and human brain DSI data acquired by a clinical 3T MR scanner within an acceptable time frame (~ 20-25 minutes).
