Intra-arterial Perfusion in Interventional Radiology

All patients will undergo standard of care locoregional intra-arterial (IA) treatment for HCC. The procedure will take place utilizing fluoroscopic and CT guidance. Following catheterization of the femoral or radial artery, CT angiography of the hepatic circulation will be performed to define the hepatic vascular anatomy. Intra-arterial CT perfusion will be performed prior to IA treatment by the interventional radiologist to understand the dynamics of hepatic circulation or to manage the IA treatment strategy.
