Native T1 mapping of autoimmune pancreatitis as a quantitative outcome surrogate

ConclusionsNative T1 mapping can be used to assess parenchymal inflammation of AIP and to quantify response to treatment. It provides a quantitative outcome surrogate for AIP.Key Points•Parenchymal inflammation in autoimmune pancreatitis results in T1 relaxation time elongation, which shortens after effective treatment.•T1 relaxation time of the pancreas correlates with serum IgG4 level, and in serum IgG4-negative AIP patients, T1 relaxation time shortening predicts clinical improvement.•T1 mapping provides a quantitative outcome surrogate for AIP.
