CT、MRI在腰椎滑脱症诊断治疗中的应用价值

目的分析CT、MRI在腰椎滑脱症诊断治疗中的应用价值。方法回顾性分析2017年1月到2018年4月100例腰椎滑脱症患者的CT、MRI影像学资料,患者均于我院确诊后行手术治疗,以手术结果为对照,分析CT、MRI的诊断价值。结果腰椎真性滑脱66例,假性滑脱34例,CT诊断敏感度及准确度均高于MRI诊断,差异有统计学意义(χ^2=11.604,10.631,P<0.05);CT影像表现为狭部裂、韧带肥厚、局部骨质增生硬化及矢状径增大椎间盘变形;MRI影像表现为狭部骨髓信号连续性中断,局部骨质T1、T2低信号,腰椎滑脱、椎间孔变形、神经根卡压及节段性椎管变性狭窄。结论选择合适的检查手段可为腰椎滑脱症的治疗赢得宝贵时间,指导诊疗方法的规范化制定,可将CT检查作为必要检查方法,MRI作为诊断补充手段。

The Application Value of CT and MRI in the Diagnosis and Treatment of Lumbar Spondylolisthesis

Objective To analyze the application value of CT and MRI in the diagnosis and treatment of lumbar spondylolisthesis. Methods CT and MRI imaging data of 100 patients with lumbar spondylolisthesis from January 2017 to April 2018 were retrospectively analyzed. All patients underwent surgical treatment after diagnosis in our hospital. Taking the surgery result as the control, the diagnosis value of CT and MRI were analyzed. Results There were 66 cases of lumbar spondylolisthesis and 34 cases of pseudoslipping. The sensitivity and accuracy of CT diagnosis were higher than those of MRI(χ^2=11.604, 10.631, P<0.05). CT images showed narrow crack, ligament hypertrophy, local hyperosteogenous sclerosis, sagittal diameter increase intervertebral disc deformation. MRI images showed continuous interruption of bone marrow signal, local bone T1, T2 low signal, lumbar spondylolisthesis, intervertebral foramen deformation, nerve root entrapment and segmental spinal canal degeneration. Conclusion Choosing appropriate examination methods can win valuable time for the treatment of lumbar spondylolisthesis, and guide development of the standardization of diagnosis and treatment methods. CT examination can be used as a necessary examination method, MRI can be used as a diagnostic supplement.
