Abstract
Fourteen patients with hepatic hemangiomas were evaluated by Tc-99m colloid scintigraphy and Tc-99m RBC [red blood cell] angiography, including flow studies and early and delayed static studies. On colloid scintigraphy the liver appeared enlarged with single or multiple focal defects. During the flow and early static Tc-99m RBC studies the lesions showed poor perfusion and were filled only partially or not at all. Delayed Tc-99m RBC studies demonstrated the extent of the lesion and all the lesions when multiple hemangiomas were present. A flow study showing decreased perfusion and a late blood-pool study showing increased local blood volume appear characteristic of hemangiomas. Liver biopsy should not be attempted in such cases.
