Scintigraphic detection of active bleeding into the intra-abdominal hematoma after percutaneous transabdominal biliary drainage using Tc-99m labeled red blood cells: A case report.

Although Tc-99m labeled red blood cells (Tc-99m RBC) imaging has been well established for localization of acute gastrointestinal bleeding, the use for detection of bleeding sites outside the gastrointestinal tract has not been widely used. The authors present a case of hemorrhage from a liver laceration successfully demonstrated using Tc-99m labeled RBC. This technique appears to be sensitive and accurate in detecting active extraintestinal hemorrhage.
