To determine the utility of perfusion MR imaging in differential diagnosis brain tumors.Fifty-seven patients with pathologically proven tumors (21 high-grade gliomas, 8 low-grade lymphomas, 6 hemangioblastomas, 7 metastases, and various other tumors) were included this study. Relative cerebral blood volume (rCBV) time-to-peak (TTP) ratios quantitatively analyzed rCBV grade each tumor was also visually assessed on an map.The highest seen followed by lymphomas. There no significant difference TTP between group (p<0.05). At visual assessment, high 17 (81%) 21 gliomas 4 (50%) gliomas. Hemangioblastomas showed lymphomas lowest.Perfusion may be helpful differentiation thevarious solid found brain, assessing glial occurring there.
