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。
Abstract
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.
