Radial sampling has been an increased application due to its insensitivity to motion. A reconstruction method combined the 3D GRAPPA operator for wider radial bands (GROWL) and narrow-band k-space weighted image contrast (KWIC) was proposed and used in GOAL-SNAP sequence. The proposed reconstruction method showed lower image RMSE, accurate T1 map estimation in simulation and higher image quality in in-vivo experiments with shorter computation time.
