Abstract:
Objective To investigate the imaging diagnostic value of the early avascular necrosis of the femoral head(ANFH) in adult.Methods There were 25 cases (34 hips) with early ANFH diagnosed by imaging and clinical data.Radiography,CT and MRI findings of ANFH were analysed comparatively.Results In the 34 ANFH included stage Ⅰ 13 hips,stage Ⅱ 21 hips.The diagnostic accurary was 32.4% for X-ray,61.8% for CT and 100% for MRI.Conclusion MRI is better than the other technique in early finding the lesions of ANFH,and the diagnostic sensitivity and accuracy of MRI are higher than that of CT and X-ray.
