Synopsis

The application of MR fingerprinting in the prostate is challenging due to the presence of image distortions produced by B0 inhomogeneities. This works presents the combination of radial sampling to minimize the effects of B0 inhomogeneity and temporal subspace reconstruction to accelerate the acquisition for fast distortionless T1 and T2 mapping in the prostate in less than 4 minutes.
