The Diagnostic Value of MSCT and MRI Imaging Parameters in Lumbar Spinal Stenosis and the Correlation with the Improvement of Lumbar Spine Function
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 canal 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)mm2,axial diameter(15.75±2.49)mm,transverse diameter(15.88±2.65)mm,dural sac area(157.59±12.72)mm2 higher than improved patients(P＜0.05),Under the MRI inspection,improved canal area(204.82±34.22)mm2,vector diameter(16.93±2.51)mm,transverse diameter(15.98±1.44)mm,dural sac area(158.77±10.51)mm2 higher than unimproved patients(P＜0.05).By ROC curve 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.
