A 3D IR radial FLASH technique and a model-based iterative algorithm for the reconstruction of undersampled data are demonstrated for efficient high-resolution T₁ mapping of the prostate. The method is insensitive to B₁ inhomogeneity and provides full coverage of the prostate volume within the time constrains of a clinical examination.
