We have evaluated the post-embolization findings of hepatic tumors(15 cases of hepatoma, and 5 cases ofmetastatic tumors)using Ivalon particles in conjunction with the pre-embolization status of CT. Serial CTexaminations were done every 3 week intervals after embolization procedure. Findings were as follows: 1. Inhepatoma, tumor volume was decreased in 7 cases at 3 week after procedure. Among which 5 cases revealed tumorvolume decrease of 0 to 25 percent. 2. Most important findings of post embolized hepatic tumors was decreasedtumoral density and attenuation of tumor wall enhancement. 3. Intratumoral air was developed within 3 week afterembolization and appeared as mottled or linear branching patterns in the center or periphery of the tumor. 4. Itseems to be important to observe the change of intratumoral density and measurement of tumoral volume to determinethe reembolizatin procedure.
