A novel sequence design based on radial fast spin echo with interleaved diffusion sensitization for simultaneous ADC and T2 mapping is presented. Additionally, a model restriction to a conventional compressed sensing reconstruction is implemented to support higher undersampling during acquisition. Simulations and phantom measurements show accurate measurement of diffusion ADC and T2 with as few as 11 spokes per TE, and 45 different TEs.
