Lumbar intervertebral discs and paraspinal muscles in 74 healthy volunteers ranging in age from 19 to 74 years were evaluated with MRI, and the occurrence of degeneration was correlated to age and body mass. Muscle size and the amount of fat in the muscles was studied from MRI cross sections. When the back muscles were degenerated, they were small and contained fat deposits. By contrast, the psoas muscles never showed gross fat deposits. Degeneration of both the lumbar discs and muscles increased with age. No correlation was found between muscle degeneration and overweight. Muscle degeneration is as common as disc degeneration in the lumbar area. MRI is an excellent method to assess both muscle and disc degeneration.
对74名年龄在19岁至74岁之间的健康志愿者的腰椎间盘和椎旁肌肉进行了MRI评估，并将退变的发生与年龄和体重相关联。从MRI横截面研究肌肉大小和肌肉中的脂肪量。当背部肌肉退变时，它们体积变小并含有脂肪沉积。相比之下，腰大肌从未出现明显的脂肪沉积。腰椎间盘和肌肉的退变均随年龄增加。未发现肌肉退变与超重之间存在关联。在腰椎区域，肌肉退变与椎间盘退变一样常见。MRI是评估肌肉和椎间盘退变的极佳方法。
