The specific correlation patterns between metabolic values, mean diffusivity and T2 relaxation times based on multivoxel analysis were observed for low and high grade gliomas, lymphomas, recurrent lesions and tissue changes by radiation/chemotherapy which enable not only tissue differentiation (healthy tissue, edema, tumor infiltrated edema, tumor; tumor recurrence vs. radiation necrosis), but also tumor type differentiation. Combination of several MR methods can be used for quantitative description of tumors to improve the outcome from MR examination of patients.
