About this study
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
18F-FAPI PET ImagingDiagnostic test
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.
| Study group | Role | What they receive |
|---|---|---|
| IBD patient group | Patients diagnosed with IBD according to clinical, imaging, endoscopic, and histopathological criteria. Receives: Diagnostic Test: 18F-FAPI PET Imaging |
What is being measured
The primary outcome is the main question the study is designed to answer.
The efficacy of 18F-FAPI PET imaging and enhanced CT in the identification of intestinal lesions in IBD was compared and evaluated
The sensitivity and specificity of PET/ CT and enhanced CT to detect endoscopic lesions were calculated and compared by receiver operating characteristic (ROC) curves.
Measured: 2025.4-2027.12
Association of 18F-FAPI imaging with endoscopic disease activity
Spearman test was used to evaluate the correlation between overall FAPI PET/CT score and IBD endoscopic range of motion (modified Mayo endoscopic score, UCEIS).
Measured: 2025.4-2027.12
The difference of FAPI SUVmax among different endoscopic MES evaluation groups
Taking into account multiple intestinal segments in each patient, mixed model ANOVA and Bonferroni-adjusted postmortem tests were performed to compare the differences in SUVmax between different MES rating groups.
Measured: 2025.4-2027.12

Questions about this trial
What is this clinical trial studying?
An observational study of Inflammatory Bowel Disease (IBD) and Disease Activity, run by Daping Hospital and the Research Institute of Surgery of the Third Military Medical University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 29 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Wenbo Li, postgraduate (+8615292886778, lwb@tmmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The efficacy of 18F-FAPI PET imaging and enhanced CT in the identification of intestinal lesions in IBD was compared and evaluated (time frame: 2025.4-2027.12). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06945549, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
