| Abstract: | Objective:To investigate the value of DWI and single voxel 1H-MRS in pediatric brain tumors.Methods:For 21 pediatric brain tumors,we used conventional MR plain and enhanced scanning,DWI and single voxel 1H-MRS imaging.ADC values were measured in three regions of interest in substantial part of the tumor on DWI,calculating the average value,Single voxel MRS regions of interest were selected in the parenchyma of the tumor(enhanced area was selected in enhanced tumors),calculating the ratio values of NAA/Cr,Ch... |
