Focal hyperemia on RBC blood-flow imaging. A scintigraphic marker of arterioportal venous shunting in hepatic cavernous hemangiomas? Clinical nuclear medicine, 1997, Volume: 22, Issue:8 To investigate the significance of increased perfusion associated with some hepatic hemangiomata during radionuclide blood volume imaging.. Immediate dynamic planar projections and delayed SPECT imaging of a hepatic lesion were obtained after the administration of Tc-99m-labeled RBC. Scintigraphic data were compared with X-ray CT, contrast angiography and postresection histopathology.. A surgically proven, cavernous hemangioma with typical findings on delayed radionuclide blood-pool imaging showed markedly increased perfusion by scintigraphy. This correlated with arterioportal venous shunting (AVPS) on contrast angiography.. Increased perfusion on radionuclide blood-volume imaging of hepatic hemangiomata may be a scintigraphic marker of AVPS. This may serve to identify patients with increased risk for spontaneous rupture or may identify them for the development of portal hypertension.
