摘　　要：目的:通过观察腰椎小关节退变的CT、常规MRI及脂肪抑制序列的影像表现,进一步提高临床对椎小关节退变的认识。方法:回顾性分析538例腰椎小关节退变的影像学资料,运用χ2检验对其每项影像学征象的CT、常规MRI及脂肪抑制序列检查结果进行统计学分析。结果:脂肪抑制序列显示关节滑膜的炎性改变优于CT和常规MRI,MRI对关节面软骨的观察优于CT(P<0.05);而CT观察骨性关节面及关节下骨质退变、关节腔真空征和伴发征象有明显优势(P<0.05);但对于骨质增生引起的椎小关节改变三者无明显统计学差异(P>0.05)。结论:对于早期或慢性期急性发作的椎小关节退变患者,应首选MRI检查并加扫脂肪抑制序列;对于慢性期或需要手术的患者,应首选CT检查。Objective：The imaging findings of CT,conventional MRI and fat saturation sequence in the lumbar articular joint degeneration were observed to further improve clinical importance.Methods：The imaging data of 538 patients with lumbar articular joint degeneration were restrospectively analysed.The results of CT,conventional MRI,and fat saturation sequence were analyzed by Chi-Square tests.Results：Fat saturation sequence was superior than CT and conventional MRI in terms of showing facet joint synovitis,MRI is better than CT in showing articular cartilage（P〈0.05）.There were obvious advantages for CT in observing bone destruction,vacuum sign,and secondary signs （P〈0.05）.But there was no significant difference in osteoarthritis among them （P〉0.05）.Conclusion：Conventional MRI and fat saturation sequence are the choice of technique for acute-inflammatory phase of disease,but CT is the choice for chronic phase or pre-operation.
