Evaluating the Effectiveness of 68Ga-grazytracer PET/CT in Inflammatory Bowel Disease

Condition(s) studied

Investigational drug(s) / intervention(s)

68Ga-grazytracer PET/CT Scan: The imaging agent 68Ga-grazytracer used in this project is synthesised in accordance with the standards for the production of radiopharmaceuticals with reference to the Chinese Pharmacopoeia (18F-FDG quality standard). pH value is between 5.0-8.0; radiochemical purity is not less than 95%, and the content of bacterial endotoxin per mL of solution is less than 15EU; the concentration of radioactivity is not less than 37MBq/mL; the solvent The residual amount of solvent complies with the regulations. Specification: 185\~1850 MBq/ml Characteristics Colourless and transparent, no visible particles. Physical half-life: 68 minutes for 68Ga. Stable for 3 half-lives from the time of labelling. Method of administration: Intravenous. Dose: 0.05Ci/kg, followed by a 5 mL saline flush.

Study summary

This is a single-centre, prospective, observational cohort study in which 69 patients with inflammatory bowel disease (IBD) were recruited to undergo 68Ga-grazytracer PET/CT imaging in patients with IBD to investigate the feasibility of early sensitive detection or prediction of the response to medication in patients with inflammatory bowel disease on 68Ga-grazytracer PET/CT and early prediction of the The feasibility of 68Ga-grazytracer PET/CT for early detection or prediction of response to drug therapy and early prediction of long-term prognosis in patients with inflammatory bowel disease.
