Many different T1 mapping sequences and extracellular volume (ECV) fraction have proven to be useful tools for evaluation of tissue fibrosis, however their potential has not been explored in abdominal imaging. We evaluated 4 different T1 mapping techniques; Dual-flip angle VIBE (DFA VIBE), MOLLI, SASHA and IR-SNAPSHOT and obtained similar ECV fractions of the liver and pancreas. DFA VIBE has the highest spatial coverage in 1 breath hold but suffers from inhomogeneous T1 in the aortic blood. IR-SNAPSHOT has advantage of not requiring cardiac gating and provides the most homogenous T1 of the blood within the aorta.
