A golden angle radial IR-FLASH technique and a principle component based iterative algorithm are developed for high-resolution T1 mapping using highly undersampled 3D radial data. The novel method yields T1 maps of a 3D volume with high spatial and temporal resolution and can cover 144 slices within 5 minutes.
