Comparison of efficiencies of magnetic resonance imaging and CT examination in diagnosis of lumbar disc herniation
Objective:To compare efficiencies of magnetic resonance imaging(MRI)and CT examination in diagnosis of lumbar disc herniation(LDH).Methods:86 patients with suspected LDH admitted to this hospital from September 2018 to August 2020 were selected as the research objects.All patients underwent MRI and CT examination.Using the results of postoperative pathological examination as the gold standard,the efficiencies of MRI and CT in the diagnosis of LDH and the detection rates of different lesion sites,lesion degrees and LDH signs were compared.Results:Among the 86 patients with suspected LDH,74 cases were confirmed as positive and 12 cases were negative by the pathological examination.There were 9 cases of L2-3,27 cases of L3-4,26 cases of L4-5 and 12 cases of L5-S1.There were 8 cases of Ⅰ degree,26 cases of Ⅱ degree,29 cases of Ⅲ degree and 11 cases of Ⅳ degree.There were 39 cases of dural sac compression,24 cases of intervertebral disc deformation,34 cases of intervertebral disc calcification,and 27 cases of nerve root compression.The sensitivity and accuracy of MRI in the diagnosis of LDH were higher than those of CT,the missed diagnosis rate was lower than that of CT,and the differences were statistically significant(P<0.05).The detection rate of L3-4 by MRI was higher than that by CT,and the difference was statistically significant(P<0.05).The detection rate of Ⅱ degree by MRI was higher than that by CT,and the difference was statistically significant(P<0.05).Further,the detection rates of dural sac compression and intervertebral disc deformation signs by MRI were higher than those by CT,the detection rate of intervertebral disc calcification signs by MRI was lower than that by CT,and the differences were statistically significant(P<0.05).Conclusions:The efficiency of MRI in the diagnosis of lumbar disc herniation is higher than that of CT.
