Measurement of regional hepatic blood flow and scintigraphic imaging of portal circulation with 133Xe

Regional hepatic blood flow has been determined by 4 methods with the aid of 133Xe washout technique: 1. scintisplenoportography (direct application of 133Xe into the spleen by means of a thin needle); 2. arterial method (133Xe is injected into the A. hepatica by means of a catheter); 3. retrograde-venous method (133Xe administered by an occluding hepatic vein catheter); 4. percutaneous intrahepatic method (133Xe administered directly into the parenchyma by means of a Chiba needle). It was possible to demonstrate that hepatic blood flow values established with the aid of 133Xe are independent of the form of application (scintisplenoportography, arterial method, retrograde-venous method).
