Objectives
Narrative objectives1
Perfusion CT is performed before and after treatment involving alteration of portal blood flow in patients with diffuse liver disease. Evaluate changes in portal vein blood flow and arterial blood flow before and after treatment, and seek to elucidate the pathology. In addition, we will elucidate the characteristics of blood flow distribution in non-cirrhotic liver diseases such as idiopathic portal hypertension (IPH), Budd-Chiari syndrome, and extrahepatic portal vein occlusion (EHO).
