Diagnostic Accuracy of ¹¹C-Methionine PET for Differentiation of Recurrent Brain Tumors from Radiation Necrosis After Radiotherapy

Abstract

(11)C-MET PET can provide quantitative values to aid in the differentiation of tumor recurrence from radiation necrosis, although these values do not appear to be absolute indicators. Quantitative analysis of (11)C-MET PET data may be helpful in managing irradiated brain tumors.
