T2 mapping is usually very time consuming and long acquisition time often result in high sensitivity to intra-scan motion. Here we propose a T2 mapping method relying on 3D radial sampling and advanced iterative reconstruction to retrospectively correct for motion and/or reduce the acquisition. First, in-vivo experiments at 3T showed the capability of the technique to correct for intra-scan motion and therefore improve the quality of resulting T2 maps. Second, acquisitions varying from 7 to 33 min of whole-brain single and multi-compartment T2 maps were obtained, showing the potential of the method to accelerate and therefore reduce sensitivity to motion.
