摘要
目的:探讨计算机断层扫描(CT)和磁共振成像(MRI)对股骨头坏死患者的诊断效果。方法:选取2018年10月-2020年10月我院治疗的100例股骨头坏死患者,均经手术病理检查确诊。所有患者均经CT、MRI检查,以手术结果为标准,比较两种诊断方法的阳性检出率、特异度与敏感度、影像学特征及阳性征象检出情况。结果:①MRI诊断阳性检出率为84.93%,高于CT诊断的76.74%(P<0.05),影像学特征与CT诊断存在差异;②MRI诊断敏感度、特异度、准确度分别为78.08%、82.14%、80.00%,均高于CT诊断的63.01%、62.96%、63.00%(P<0.05);③MRI诊断阳性征象检出率为85.00%,高于CT诊断的62.00%(P<0.05)。结论:在股骨头坏死诊断中,MRI诊断阳性检出率高于CT诊断,效果理想。
Objective:To investigate the effect of computed tomography(CT)and magnetic resonance imaging(MRI)on patients with femoral head necrosis.Methods:A total of 100 patients with femoral head necrosis treated in our hospital from October 2018 to October 2020 were selected and were diagnosed by surgical pathological examination.All patients were examined by CT and MRI,and the surgical results were used as the standard to compare the positive detection rate,specificity and sensitivity,and imaging characteristics of the two diagnostic methods.Results:(1)The positive detection rate of MRI diagnosis was 84.93%,which was higher than 76.74%of CT diagnosis(P<0.05).There were differences between imaging features and CT diagnosis.(2)The sensitivity,specificity and accuracy of MRI diagnosis were 78.08%and 82.14%,respectively 80.00%,higher than 63.01%,62.96%,63.00%of CT diagnosis(P<0.05);(3)The detection rate of positive signs in MRI diagnosis was 85.00%,higher than 62.00%of CT diagnosis(P<0.05).Conclusion:In the diagnosis of femoral head necrosis,the positive detection rate of MRI diagnosis is CT diagnosis,and the effect is ideal.
