Résumé

Use compressed sensing (CS) for 3D biexponential spin-lattice relaxation time in the rotating frame (T Fully sampled 3D-T Most CS methods performed satisfactorily for an acceleration factor (AF) of 2, with relative median normalized absolute deviation (MNAD) around 10%. Some sparsifying transforms, such as low rank with spatial finite difference (L + S SFD), spatiotemporal finite difference (STFD), and exponential dictionaries (EXP) significantly improved this performance, reaching MNAD below 15% with AF up to 10, when spatial filtering was used. Accelerating biexponential 3D-T
