Evaluation of Hepatic Hemangioma with Tc-99m Labeled Red Blood Cells

Abstract

Six patients with cold defects on sulfur colloid liver/spleen scans and no history suggestive of malignant disease were imaged with Tc-99m in vivo labeled red blood cells. Dynamic, immediate, and delayed static images of the liver were obtained on all patients, demonstrating accumulation of activity in the lesions over time in five patients. This correlates well with the suspected diagnosis of hepatic hemangioma. We suggest using this simple, non-invasive technique for evaluating the presence and the extent of hepatic hemangiomas.
