Abstract：Objective To study diffusion weighted imaging features of medulloblastoma in children.Mtehods Imaging find-ings of 72 children with medulloblastoma were retrospectively reviewed .The patients included 44boys and 28 girls, ranging in age of onset from 1 to 18 years.All the 72 patients were examined with pre-contrast and post-contrast T 1 weighted MR imaging, non-contrast T2 weighted MR imaging, and diffusion weighted imaging.Medulloblastoma was confimed by pathologic examinations in the 72 patients.Results Among 72 cases with melulloblastoma, 61 cases’ lesions were located at the cerebellar vermis, and other 11 cases’ lesions were in the cerebellar hemisphere.All cases showed iso-signal or low-signal on both T1 weighted MR ima-ges and high-signal on T2 weighted MR images.And all cases were enhanced at different extension.The precision rate of imaging diagnosis report was 74%.Conclusion Medulloblastoma in children has a typical predilection in location and characteristic ima -ging findings.Knowing well the imaging findings of medulloblastoma and useing diffusion weighted imaging may help us to improve imaging diagnostic accuracy.
