Evaluation of Intrahepatic Perfusion on Fusion Imaging Using a Combined CT/SPECT System: Influence of Anatomic Variations on Hemodynamic Modification Before Installation of Implantable Port Systems for Hepatic Arterial Infusion Chemotherapy

摘要

In some patients with hepatic tumors, anatomic variations in the hepatic arteries may require hemodynamic modification to render effective hepatic arterial infusion chemotherapy delivered via implantable port systems. We used a combined CT/SPECT system to obtain fused images of the intrahepatic perfusion patterns in patients with such anatomic variations and assessed their effects on the treatment response of hepatic tumors.
