To investigate the value of MRI characteristics in the differential diagnosis of hemangiopericytoma and angiomatous meningioma.15 cases of AM and 11 cases of the HPC which were confirmed by pathology. MRI sequences were routinely available. The mean ADC values of HPC was signi´Čücantly higher than that of AM (t = 2.613, p =0.02). The mean CBF values (t= -8.99, P<0.01) and FA values (t= -3.66, P<0.01) were lower for HPC compared with AM. MRI imaging characteristics of HPC and AM have significant difference. Combining structural MRI comparative analysis and functional MRI was useful for distinguishing HPC from MA.
