| Research Abstract |
Heterogeneity is a recognized characteristic of malignant tumor. It has been reported to be associated with factors that influence resistance to therapy such as histological features including cellular proliferation, necrosis, and physiological features including degree of vascularity, gene expression, energy metabolism, and oxygenation. All these aspects of intratumoral heterogeneity may affect the biological behavior of tumors in patients, which may manifest as variability in prognosis and treatment response. The purpose of this study was to quantitatively measure intratumoral heterogeneity, and to delineate the differences in the distribution of F-18 FDG, F-18 FLT, and C-11 methionine in patients with primary brain tumors.
