Inflammatory bowel disease detection enhanced with PET/CT
Date:5/1/2013

Crohn's patients were retrospectively analyzed, and the findings were then correlated to endoscopic procedures performed before or after the CT without any interfering treatments. In accordance with the results in the DSS colitis, an increased 18F-FDG uptake was found in 87 percent of deep mucosal ulcerations, whereas mild endoscopic lesions were detected in approximately 50 percent of patients assessed.

"In Crohn's disease patients, 18F-FDG PET/CT seems to accurately detect advanced inflammatory changes and also unmask subepithelial disease activity that might be missed by colonoscopy. Therefore, PET/CT might serve as an additional tool for evaluating disease activity in IBD patients, e.g., in defining complete remission," noted Bettenworth.

Michael Schfers, MD, senior author of the study, added, "Using a clinically established tracer, the translation of this approach into daily clinical routine should benefit patients in the near future and will further promote the use of PET/CT for new indications in clinical algorithms."

Crohn's disease and ulcerative colitis are chronic-remittent, inflammatory conditions featuring characteristic mucosal lesions within the bowel leading to diarrhea, stricture formation, abdominal pain and weight loss. Crohn's disease may affect as many as 700,000 Americans, and ulcerative colitis may affect up to an additional 700,000; incidence rates for these diseases are on the rise worldwide.
