Purpose To develop and evaluate a variable‐flip‐angle golden‐angle‐ordered 3D stack‐of‐radial MRI technique for simultaneous proton resonance frequency shift (PRF) and T1‐based thermometry in aqueous and adipose tissues, respectively. Methods The proposed technique acquires multiecho radial k‐space...
