99mTc-Macroaggregated Albumin SPECT/CT Perfusion Imaging of Omental Extrahepatic Vascularization.

The authors present a case of omental perfusion by an extrahepatic branch of the right hepatic artery depicted during pre-embolization planning with 99mTc-macroaggregated albumin SPECT/CT imaging. This omental scintigraphic finding corresponds to an extrahepatic branch of the right hepatic artery demonstrated by selective angiography and related CT angiography. The authors would like to add the omentum to the previously reported sites of extrahepatic vascularization encountered during the hepatic pre-embolization imaging.
