Three-Dimensional (3D) sequence of magnetic resonance imaging (MRI) plays a critical role in musculoskeletal joints imaging; however, its long acquisition time limits the clinical application. In such condition, Compressed sensing (CS) is introduced to accelerate MRI during clinical practice. We aimed to investigate the feasibility of an isotropic 3D variable-flip-angle fast spin echo (FSE) sequence with CS technique (CS-MATRIX) compared to conventional 2D sequences on knee imaging.
