ABSTRACT
Objective To investigate the conventional MRI and perfusion weighted imaging (PWI) features of central neurocytoma(CNC), and to evaluate the potentiality of them in diagnosing accuracy. Methods Three patients with CNC proved pathologically were collected, 4 patients with ependymoma were as control group, with conventional MRI and perfusion weighted imaging were performed in all of them. MRI features were observed, and relative regional cerebral blood volume (rrCBV) were calculated.Results CNCs were isosignal on T_1WI, hyperintense on T_2WI, minimal enhancment. Ependymomas were hypointense or isosignal on T_1WI, slightly hyperintense or hyperintense on T_2WI and minimal enhancement. On PWI, CNCs were obviously high-perfusion, rrCBV was 11.2, but which was 2.1 in ependymoma, there was statistically signifcant difference between two groups(P
