Analysis on Diagnosis Value of MRI in Early Femoral Head Necrosis
LU Chun
Abstract：Objective:To investigate the diagnosis value of MRI in early femoral head necrosis.Method:From January 2014 to November 2015,52 patients(66 hips) diagnosed with femoral head necrosis underwent total hip arthroplasty in our department were selected as the objects,all the patients were diagnosed by X-ray and MRI preoperatively,the positive rates of this two diagnostic methods were compared.Result:38 cases(51 hips) were diagnosed positively in 52 patients(66 hips) by X-ray,the positive rate was 73.1%(38/52),while the positive rate was 96.2%(50/52) by MRI.6 cases were misdiagnosed by X-ray, the misdiagnosis rate was 11.5%(6/52),while 2 cases were misdiagnosed by MRI,the misdiagnosis rate was 3.8%(2/52),the differences were statistically significant(P<0.05).Conclusion:MRI has higher sensitivity and specificity in the diagnosis of early femoral head necrosis,which is valuable in clinical application.
