The correlation between the change of Hounsfield units value and Modic changes in the lumbar vertebral endplate

Table 3 The mean HU value of BMD groups

BMD group	Osteoporosis group	Osteopenia group	Normal group
Mean T-score	−2.70 ± 0.20	−1.46 ± 0.37	−0.38 ± 0.60
Mean HU value	401.46 ± 104.46**	545.70 ± 123.52**	659.86 ± 156.17**

**The HU value of endplate was significant positively correlated with T-score (r = 0.467, p < 0.001), and the mean HU value of endplate was significantly different in three groups (p < 0.001)
