| Outline of Final Research Achievements |
As a result of our in vitro studies, a suspension made of an isobaric ethiodized oil contrast medium adjusted to have an equal specific gravity as human blood has lower viscosity than the suspension made of a high specific gravity oil contrast medium so that it might be a useful material for the transcatheter arterial chemoembolization or the hepatic arterial infusion chemotherapy for primary hepatocellular carcinoma or metastatic hepatic tumors.
In addition, our in vivo studies showed that isobaric ethiodized oil contrast medium was less effected the gravity effect and more evenly distributed after arterial injection compared with conventional high specific gravity oil contrast medium.
