We demonstrated the feasibility of golden-angle radial MR fingerprinting for high-resolution quantitative multi-parametic prostate MRI. The variation in T1 and T2 values for different scan times within the normal prostate and the required number of spokes per temporal time frame required for robust quantitation parameter mapping were examined. A decrease in average T1 and T2 values was observed as scan time increased. Radial spokes of 2 or more per temporal frame achieved parameter maps that are in good agreement with reported normal prostate transition zone values.
