Tc-99m HMPAO labeled donor leukocyte scan in liver transplant

Tc-99m HMPAO labeled donor leukocytes were used to image the focus of an hepatic infection in a 32-year-old liver transplant patient. Six hours after the administration of labeled leukocytes, radioactivity accumulation was detected in the liver suggesting an intrahepatic infection focus. Diagnosis of infection was confirmed at surgery.
