Comparison of CT and MRI in the Diagnosis of Femoral Head Necrosis

Objective To investigate the clinical diagnosis of femoral head necrosis by CT and MRI.Methods From April 2018 to April 2019,150 patients with femoral head necrosis were enrolled in the hospital.As subjects in this study,MRI and CT were diagnosed after admission,and two different diagnostic methods were statistically analyzed.Results The diagnostic accuracy of MRI was 96.67%,and the accu racy of CT diagnosis was 72.00%.The difference was very significant(P<0.05).Among them,M RI detected 46 cases of stage Ⅰ,47 cases of stage Ⅱ,50 cases of stage Ⅲ,and 2 cases of stage IV.CT detected 27 cases of stage Ⅰ, 39 cases of stage Ⅱ,41 cases of stage Ⅲ,and 1 case of stage IV.The detection rate of early positive signs of MRI(single cystic change,line-like sign,and trabecular bone structure) was higher than CT(P<0.05).MRI diagnostic sensitivity was higher than CT(P<0.05),but MRI diagnostic specificity was not significantly different from CT(P>0.05).The Kappa consistency of MRI and CT was>0.5,suggesting a high consistency between MRI and CT diagnosis.Conclusion Both MRI and CT can effectively diagnose femoral head necrosis.However,the diagnostic value of MRI is significantly higher than that of CT,which can further effectively observe the actual condition of femoral head necrosis,thus providing a reliable basis for clinical effective diagnosis and treatment.It is worth recommending in the clinic.
