Acquisition schemes based on gradient and spin-echo (GRASE) methods have been developed for the fast fat-water and T2 estimation. In this work we present a variable bandwidth radial GRASE (VB-radGRASE) sequence with the goal of optimizing the SNR of T2 and fat-water parameter estimation. The new method is evaluated in phantoms and in vivo data.
