There has been renewed interest in the estimation of T1 relaxation times as a quantitative method for characterization of pathologies in the abdomen. While various techniques have been presented for T1 mapping they have not been systematically evaluated. In this work, we present a multi-slice radial Look-Locker FLASH technique for robust and reproducible abdominal T1 mapping. We investigate the effect of various pulse sequence and reconstruction parameters on the T1 estimation performance.
