腰椎退行性疾病中椎旁肌肉脂肪浸润的影像学评估方法
Imaging Evaluation Methods for Fat Infiltration of Paravertebral Muscles in Lumbar Degenerative Diseases

目的：对椎旁肌肉脂肪浸润的影像学评估方法的优缺点，和它与腰椎退行性病变的相关性等进行了综述。方法：广泛查阅国内外关于椎旁肌肉脂肪浸润评估方法、椎旁肌肉退变与腰椎疾病的相关文献，对常用的椎旁肌肉脂肪浸润评估方法优点和局限性等方面、椎旁肌肉退变与腰椎疾病的关系进行总结。结果：CT、MRI常被用于评估脂肪浸润程度，并且可靠性较好；影像学评估方法各有优缺点。研究表明脂肪浸润能更好地代表肌肉退变，椎旁肌肉退变与多种腰椎疾病相关。结论：椎旁肌肉的脂肪浸润评估方法多样，但不同研究结果之间存在差异，缺乏统一标准，希望未来能够建立统一的评估体系，对临床诊疗提供帮助。
Objective: To review the advantages and disadvantages of imaging methods for assessing fat infiltration of the paravertebral muscles and their relationship to degenerative lumbar spine disease. Methods: We extensively reviewed domestic and international literature on paraspinal muscle fat infiltration assessment methods, paraspinal muscle degeneration and lumbar spine diseases; we summarized the advantages and limitations of commonly used paraspinal muscle fat infiltration assessment methods, and the relationship between paraspinal muscle degeneration and lumbar spine diseases. Results: CT and MRI are commonly used to assess the extent of fat infiltration with good reliability. The imaging evaluation methods have their own advantages and disadvantages. Studies have shown that fat infiltration better represents muscle degeneration and that paraspinal muscle degeneration is associated with a variety of lumbar spine disorders. Conclusions: The fat infiltration of paravertebral muscles is assessed by various methods, but there are differences between the results of different studies and a lack of uniform standards, and we hope that in the future we can establish a uniform assessment system to help clinical diagnosis and treatment.
