New scan could help Crohn's patients avoid unnecessary surgery

This study is testing a special PET/MR scan that uses a radioactive tracer to detect scar tissue in the bowel of people with Crohn's disease. The goal is to see if the scan can tell the difference between scarred (fibrotic) strictures and inflamed ones, which would help doctors decide whether surgery or medication is the better option. Twenty-five adults with Crohn's disease who are already scheduled for possible surgery will receive the tracer and undergo the scan, and the results will be compared with what surgeons find during the operation.
