Abstract: Systems and methods are disclosed for a simultaneous 3D T1 and B1+ mapping technique based on VFA imaging using a reference region VFA (RR-VFA) approach to eliminate the need for a separate B1+ mapping scan while imaging the prostate. The RR-VFA method assumes the existence of a “reference region” that is distributed throughout the volume of interest and is well characterized by a known T1 relaxation time. In particular, fat is generally selected as the reference region due to its distribution in the body. B1+ inhomogeneity is estimated in the fat tissue and interpolated over the entire volume of interest, thus eliminating the need for an additional scan.
