Cultured human glioma initiating cells (GIC) were stereotactically injected into the striatum of immunodeficient nude rats. The developed tumors were characterized by T2-weighted and contrast enhanced T1-weighted imaging. Cerebral metabolism in the tumors was studied using high-field 1H magnetic resonance spectroscopy leading to the identification and quantification of 15 metabolites representative of tumor growth and metabolism.
