This investigation evaluates the performance and accuracy of a fast inversion recovery Look-Locker method for in vivo liver T1 mapping. Several parameters were assessed using T1 phantoms to describe accuracy trends and prevalence for artifacts. The method was also applied in vivo to demonstrate feasibility of fast T1 mapping of liver parenchyma and blood pool. The results offer insight into optimal imaging parameters, and showed good agreement with known T1 values at 1.5T.
