OBSERVATIONAL
Conditions
Summary
The goal of this observational study is to evaluate the role and effect of 18F-FAPI PET imaging in the identification of intestinal lesions and the assessment of disease activity in inflammatory bowel disease. The main question it aims to answer is: Can 18F-FAPI PET imaging effectively identify intestinal lesions in inflammatory bowel disease and accurately assess disease activity? Colonoscopy, enhanced abdominal CT, and 18F-FAPI intestinal imaging were completed within 1 week, and major adverse outcomes (MAO) were followed up 12 months after enrollment.

Interventions
The ROI of the target lesions was delineated based on 18F-FAPI PET Imaging, and the lesions were divided on the cross section to obtain the lesions SUVmax, SUVmean, SUVpeak, FAPI metabolic volume (FAV), MTV, TBR, and TLG.
