Utility of FDG PET/CT in assessing bowel inflammation.

Purpose: To develop a methodology for the quantification of gastrointestinal (GI) inflammation as indicated by 2-deoxy-2-(F)fluoro-D-glucose (FDG) uptake on positron-emissions tomography/computed tomography (PET/CT) imaging. This is intended to investigate the feasibility of using standard uptake value (SUV) levels to assess levels of GI inflammation in humans.

Methods: 131 participants were injected with a weight-controlled dose of FDG 180 minutes prior to PET/CT scanning.
