Celiac Artery Stenting to Facilitate Hepatic Yttrium-90 Radioembolization Therapy

Figure 4

During the mapping angiogram phase, 5 mCi of technetium-99m labeled macroaggregated albumin was injected within the right hepatic artery to quantify the liver-lung shunt. The planar scintigraphic images demonstrate distribution of the radiotracer within the right lobe of the liver without any abnormal extrahepatic distribution. Regions of interest were drawn within the lungs and liver resulting in an estimated maximum lung shunting of 3%.
