T1 relaxation mapping has been shown to demonstrate significant differences in the pancreas of patients with chronic pancreatitis. However, T2 and T1ρ relaxation times have been largely unexplored in pancreas, due to difficulty acquiring these values in the abdomen. In this study, magnetic resonance fingerprinting (MRF) techniques are applied to simultaneously acquire T1, T2, and T1ρ relaxation times in the pancreas of healthy volunteers and patients with clinically diagnosed chronic pancreatitis (CP). A significant increase in T1 relaxation was found with near significant increases in T2 and T1ρ relaxation times in CP patients.
