Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with a documented diagnosis of inflammatory bowel disease who can undergo PET/CT, colonoscopy, and enhanced abdominal CT within one week and who consent to 12-month follow-up.

Probably not a fit

Pregnant or lactating individuals, patients with unusable imaging quality, and those who cannot safely undergo endoscopy or CT are excluded and unlikely to benefit from this imaging approach.

What this trial studies

This observational study enrolls adults with a confirmed diagnosis of IBD who undergo 18F-FAPI PET/CT, colonoscopy, and enhanced abdominal CT within one week so imaging and endoscopic findings can be directly compared. Investigators will match intestinal segments across modalities to determine how well FAPI PET identifies lesions and correlates with clinical disease activity. Poor-quality images and contraindications to endoscopy or CT are exclusion criteria. Participants will be followed for 12 months for major adverse outcomes to explore whether baseline imaging predicts clinical course.

Why it matters

Potential benefit: If successful, FAPI PET could provide a less invasive and potentially more sensitive way to locate intestinal lesions and monitor disease activity, which might reduce the need for repeated colonoscopies.

How similar studies have gone: Early pilot and small cohort studies of FAPI PET in inflammatory and fibrotic conditions have shown promising lesion localization, but large-scale validation specifically in IBD remains limited.
