The absorption values of cancellous bone of the third lumbar vertebral body were measured in 80 patients by CT. It was possible to demonstrate a statistically significant linear correlation between absorption values and patient age. The older the patient, the lower the average absorption values of cancellous bone. The average absorption values in patients between 20 and 30 Jrs. were found to be about 200 HU, between 30 and 50 Jrs. 180, between 60 and 70 Jrs. 120 and between 70 and 80 Jrs. 100 HU. Although correlation between calcium salt content and absorption of bone under CT are well known, there are other factors (mainly fatty involution of bone marrow) who influences the absorption behaviour of cancellous bone.
通过CT测量了80例患者第三腰椎椎体松质骨的吸收值。结果表明，吸收值与患者年龄之间存在统计学上显著的线性相关性。患者年龄越大，松质骨的平均吸收值越低。20至30岁患者的平均吸收值约为200HU，30至50岁患者为180HU，60至70岁患者为120HU，70至80岁患者为100HU。虽然CT下骨盐含量与骨吸收之间的相关性是众所周知的，但还有其他因素（主要是骨髓脂肪退变）会影响松质骨的吸收行为。
