The Role of MR Enterography in Assessing Crohn’s Disease Activity and Treatment Response

Figure 5

Simultaneous ¹⁸F-FDG PET/MR in a patient with known Crohn’s disease. (a) Axial T1-weighted fat-saturated postcontrast images with mucosal hyperenhancement of several loops of small bowel in the lower abdomen consistent with active inflammation. (b) Attenuation-corrected PET images demonstrate intense ¹⁸F-FDG uptake in these bowel loops. (c) Fusion overlay images demonstrate localization of ¹⁸F-FDG avidity to the enhancing small bowel loops.
