Comparative analysis of 3.0T magnetic resonance imaging and CT in diagnosis of low lumbar disc herniation in elderly patients
Objective:To compare and analyze the diagnostic value of 3.0T magnetic resonance imaging and CT in elderly patients with low lumbar disc herniation.Methods:63 patients with suspected low lumbar disc herniation admitted to our hospital from May 2021 to March 2023 were selected.The final clinical diagnosis was taken as the gold standard.All patients underwent 3.0T magnetic resonance imaging and CT examination,and the diagnostic results,diagnostic efficacy and imaging results of low lumbar disc herniation were observed and compared.The bone parameters of the two methods were compared.Results:The rates of disc degeneration,spinal cord degeneration and dural sac compression in 3.0T MRI were higher than those in CT(P<0.05),and the rates of calcification and air accumulation in CT were higher than those in 3.0T MRI(P<0.05).The facet joint Angle and lumbosacral Angle of 3.0T MRI were higher than those of CT,lumbar curvature and L5S1 disc height were lower than those of CT(P<0.05).The diagnostic sensitivity and accuracy of 3.0T MRI were higher than that of CT,and the missed diagnosis rate was lower than that of CT.The Kappa value of 3.0T magnetic resonance imaging in diagnosing different types of low lumbar disc herniation was higher than that of CT.Conclusion:3.0T magnetic resonance imaging has obvious advantages in the diagnosis of disc degeneration,spinal cord degeneration,dural sac compression and nerve direction,and the detection rate of CT is higher in the diagnosis of calcification and air accumulation.Therefore,the clinical diagnosis of lumbar disc herniation can be combined with the advantages of the two examination methods according to the specific conditions.
