Metabolic response after intraarterial 90Y-glass microsphere treatment for colorectal liver metastases: comparison of quantitative and visual analyses by 18F-FDG PET.

Abstract

It is feasible to quantify reduction of hepatic tumor metabolism objectively after (90)Y treatment for unresectable metastatic disease to the liver. SUVs of the entire axial slices of liver agree well with subjective visual evaluations. Quantitative PET is a useful technique in the treatment response evaluation of patients after (90)Y-glass microspheres.
