Background Stack‐of‐radial multiecho gradient‐echo MRI is promising for free‐breathing liver R2* quantification and may benefit children. Purpose To validate stack‐of‐radial MRI with self‐gating motion compensation in phantoms, and to evaluate it in children. Study Type Prospective. Phantoms Four vi...
