Synopsis

We investigated the usefulness of native T1 mapping using a modified look-locker inversion recovery (MOLLI) sequence, which can be used to evaluate Crohn's disease (CD). The nativeT1 value was measured by setting an ROI on the intestinal wall of the nativeT1 map containing the short-axis image of the intestine. Simple endoscopic activity score in CD (SES-CD) was used as the reference standard for evaluating CD activity. A strong correlation was found between native T1 value and the SES-CD (r = 0.83; p = 0.001).
