It is generally accepted that continuous infusion of anti-cancer agent is a good procedure for patients withmetastatic liver tumor. We studied the relationship between Tc-99m MAA scintigraphy patterns in the liverand the effect of intra-arterial chemotherapy for metastatic liver tumor. Scintigraphy was obtained after injectionof 185 MBq of Tc-99m MAA into catheters, and compared with the liver scintigraphy using Tc-99mphytate. The Tc-99m MAA imagings were graded to three patterns; 'High', 'Ring', or 'Low'. We estimatedthe relationship between Tc-99m MAA patterns and the effect on 3 months after the start of chemotherapy.Out of 18 'High' cases, partial remission (PR) or complete remission (CR) were obtained in 13 cases (72.2%).'High' or 'Ring' patterns showed the significantly higher efficacy than 'Low' pattern . We concluded that Tc-99m MAA scintigraphy might have a role in prediction of efficacy on intra-arterial chemotherapy.
