[Change in lobar uptake of 99mTc-galactosyl serum albumin after transarterial embolization therapy].

Liver function was studied by hepatic scintigraphy with 99mTc-galactosyl serum albumin (GSA) before and after transarterial embolization (TAE) therapy in 16 patients with hepatocellular carcinoma. The percent uptake of GSA in liver was measured separately in the treated and non-treated areas. GSA uptake increased in both areas. The change was more marked in the non-embolized lobe than the embolized lobe. We conclude that the increase in GSA uptake reflects the regeneration of liver cells after TAE.
