Cerebral lymphomas are sometimes difficult to distinguish from glioblastomas based on routine magnetic resonance (MR) examination. Therefore, this study assessed the utility of a histogram analysis of the intratumoral enhanced region, using contrast-enhanced T1WI (CET1WI) with a 3D-spoiled gradient recalled aquisition in the steady state (SPGR) sequence, for cerebral lymphomas and glioblastomas, to determine whether the histogram parameters differed between the two tumors. There was significant difference (p < 0.01) in skewness between lymphomas and glioblastomas. This suggests the possibility of differential diagnosis of cerebral lymphomas and glioblastomas by histogram analysis of CET1WI.
