Simultaneous splenic and hepatic scintigrams were performed with technetium Tc 99m colloid on 19 patients who had sustained abdominal trauma. Five cases of splenic hematoma were diagnosed; all were confirmed and successfully treated. Three cases of liver hematoma were diagnosed; two were confirmed, and all were successfully managed. There is no evidence that the procedure failed to detect clinically significant lesions of the liver or the spleen.
