The compressed sensing (CS) technique, which implements k-space sparses ampling and iterative reconstruction algorithm, has now been widely used in acceleration of MR examinations of various anatomies and anatomical contrasts. This study aims to explore the performance of 3D water-fact imaging accelerated using a combination of compressed-sensing and sensitivity encoding on kidney of healthy subjects. Several acceleration factors of the proposed technique were compared against the traditional sensitivity-encoding technique and an acceleration factor of 2 was recommended for a balance between imaging time and image quality.
