Imaging Modalities for the Noninvasive Assessment of Fibrosis in Crohn's Disease

(a) MR enterography, T2 weighted sequence (HASTE, half-Fourier axial single-shot fast spin-echo): relapse of segmental disease associated with segmental wall thickening at the site of previous ileocolic anastomosis; (b) MR enterography T2 weighted sequence (TrueFISP, true fast imaging with steady-state free precession) delineated profiles of segmental wall thickening and mild comb sign; (c-d) MR enterography, T1-weighted sequence (VIBE, volumetric interpolated breath-hold examination): postcontrast homogeneous enhancement of the intestinal wall suggesting a fibrotic lesion.
