Quantitative R2 and R2* maps are critical for a wide range of applications. The GESFIDE sequence can provide simultaneous R2 and R2* information. However, for abdominal imaging, application of this method can be particularly challenging due to respiratory motion. We developed a GESFIDE-PROPELLER approach for simultaneous R2 and R2* measurements in the abdomen and demonstrated that GESFIDE-PROPELLER can provide accurate R2 and R2* measurements while reducing respiratory motion artifacts.
