We evaluated age-related changes in the morphometric features of lumbar vertebrae in both sexes using magnetic resonance imaging (MRI). Midsagittal MRI scans of 366 individuals (156 mates, 210 females; 25-82 years old) were evaluated retrospectively. The anterior height (H-a), central. height (H-c), posterior height (H-p), and anteroposterior diameter (D) of the body of each tumbar vertebra were measured. These measurements were used to calculate three indices, namely, the anterior wedge index (H-a/H-p), the biconcavity index (H-c/H-p), and the compression index (H-p/D).
