The differentiation of oligodendroglioma and astrocytoma has become increasingly important due to the distinct sensitivity of oligodendroglioma (OD) to chemotherapy and prolonged survival compared to astrocytoma (AT) of similar grades. The purpose of the present study was to determine whether unique characteristics of OD and AT are visible on MR imaging and to assess the added value of perfusion imaging in differentiating OD from AT tumors across similar grades in large study population. Our results demonstrated no characteristic/specific conventional MRI features and perfusion parameters those could clearly differentiate similar grades of OD’s and AT tumors.
