**5.2 Tc-99m labelled Anti-granulocyte antibody: Imaging protocols and pre-requisites**

Tc-99m Sulesomab is presented as a lyophilised powder (0.31 mg per vial) to be reconstituted with sodium chloride. Approximately 555-925 MBq is injected intravenously. Imaging should be performed 1–8 hours post injection. We usually perform imaging at 10 minutes and 2-4 hours post injection with occasional 24 hour delayed imaging in certain situations to have better target to background ratio for better delineation of lesions.
