Atlas of 99mTc Labeled Red Blood Cell Liver Scintigraphy

Technetium-99m labeled red blood cell (99mTc RBC) scintigraphy has been found extremely useful for the diagnosis of cavernous hemangiomas of the liver. This atlas chapter will briefly review the pathophysiology, clinical manifestations, and importance of these benign tumors. The diagnostic role of other imaging modalities, such as ultrasonography, CT, and MRI will be discussed. Emphasis will be placed on the overall accuracy and clinical utility of 99mTc RBC planar and SPECT scintigraphy. Examples in the Atlas Section will emphasize important diagnostic teaching points.
