摘　　要：目的探索MSCT及MRI影像参数在腰椎管狭窄症的诊断价值及与腰椎功能改善的相关性。方法回顾性分析的80例腰椎管狭窄症患者(观察组)、81例非腰椎管狭窄症者(对照组)均在2020年5月至2023年4月期间收集,均进行了MSCT、MRI检查,比较两组各影像参数(椎管面积、椎管矢径、椎管横径、硬膜囊面积),再针对观察组腰椎功能改善情况分为两组,即改善者(n=58),未改善者(n=22),比较两组MSCT及MRI的影像参数。结果MSCT检查下,改善患者椎管面积(202.87±36.43)mm^(2)、椎管矢径(15.75±2.49)m m、椎管横径(15.88±2.65)mm、硬膜囊面积(157.59±12.72)mm^(2)高于未改善患者(P<0.05),MRI.检查下,改善患者椎管面积(204.82±34.22)mm^(2)、椎管矢径(16.93±2.51)mm、椎管横径(15.98±1.44)mm、膜囊面积(158.77±10.51)mm^(2)高于未改善患者(P<0.05)。经RDC曲线分析,MSCT椎管面积、椎管矢径、椎管横径、硬膜囊面积预测腰椎管狭窄症患者腰椎功能改善情况的AUC分别为0.762、0.620、0.788、0.795。MRI椎管面积、椎管矢径、椎管横径、硬膜囊面积预测腰椎管狭窄症患者腰椎功能改善情况的AUC分别为0.806、0.796、0.874、0.880。结论MSCT、MRI在预测腰椎管狭窄症患者腰椎功能中均具有较高效能。Objective To explore the diagnostic value of MSCT and MRI imaging parameters in lumbar spinal stenosis and the correlation with the improvement of lumbar spine function.Methods The retrospective analysis of 80 patients with lumbar spinal stenosis(observation group)and 81 patients with non-lumbar spinal stenosis(control group)were collected from May 2020 to April 2023,and compared the imaging parameters of the two groups(spinal ca nal area,sagittal diameter,transverse canal diameter,dural sac area),and divided the two groups in the observation groups,namely improvement(n=58)and unimproved(n=22),and compared the imaging parameters of MSCT and MRI of the two groups.Results Under the MSCT examination,Improving spinal area(202.87±36.43)mm^(2),axial diameter(15.75±2.49)m m,transverse diameter(15.88±2.65)mm,dural sac area(157.59±12.72)mm^(2)higher than improved patients(P<0.05),Under the MRI inspection,improved canal area(204.82±34.22)mm^(2),vector diameter(16.93±2.51)mm,transverse diameter(15.98±1.44)mm,dural sac area(158.77±10.51)mm^(2)higher than unimproved patients(P<0.05).By ROC cu rve analysis,the AUC of MSCT spinal area,vector diameter,transverse diameter,and dural sac area predicting the improvement of lumbar function in patients with lumbar spinal stenosis was 0.762,0.620,0.788,and 0.795,respectively.The AUC of MRI spinal canal area;spinal vector diameter,spinal transverse diameter,and dural sac area predicting the improvement of lumbar spine function in patients with lumbar spinal stenosis were 0.806,0.796,0.874,and 0.880,respectively.Conclusion MSCT and MRI are highly effective in predicting lumbar spine function in patients with lumbar spinal stenosis.
