Figure 1.BMI, micro-CT based three-dimensional images and histomorphometry in aged female SD rats. BMI (A), three-dimensional reconstruction (B), bone volume (BV), bone surface density (BV/TV), ratio of bone surface area to bone volume (BS/BV), trabecular number (Tb.N), trabecular thickness (Tb.Th), and trabecular spacing (Tb.Sp) using micro-CT scanning (C–H). Results were compared by unpaired t test with Welch’s correction, *P < 0.05, #P < 0.01.
