Abstract: Objective To assess the value of MRS in evaluating vertebral bone marrow. Methods A total of 152 female volunteers (mean age 58±14 years, ranged 30～80 years) were recruited in this study. All subjects underwent vertebral MRS examination after routine MRI examination (sagittal T_2WI, T_1WI and axial T_2WI). Single voxel (SV) was chosen for the 1H MRS acquisition at L_2～L_4 vertebral body with PRESS sequence. MRS parameters were measured by SAGE 7.0 software. Results The fat fraction (FF%) of vertebra ascend with aging;the water line width (LW) decrease with aging and there was not obvious tendency with lipid LW. Conclusion Vertebral MRS can be considered as a noninvasive examination added to routine spine MRI to demonstrate the changes of vertebral bone marrow.
