Evaluation of inflammatory bowel disease with 99mTc-DTPA

99mTc-DTPA was found to localize in segments of bowel with inflammation due to ulcerative colitis, regional enteritis, and other forms of enterocolitis. The concentration of tracer was apparently related to the clinical activity of the disease process. Imaging with 99mTc-DTPA may offer an appealing, noninvasive alternative for identifying and following up patients with inflammatory bowel disease.
