磁共振在股骨头坏死诊断中的临床研究

Clinical study of magnetic resonance imaging in the diagnosis of avascular necrosis of femoral head

目的：探究磁共振在股骨头坏死诊断中的临床价值。方法：收治股骨头缺血性坏死患者153例，行磁共振检查，对医学影像进行全面分析。结果：共计189个股骨头发生病变，0期25个，Ⅰ期63个，Ⅱ期26个，Ⅲ～Ⅳ期39个。关节面异常，发生塌陷，骨质被破坏，关节间隙变小。结论：磁共振技术在诊断缺血性股骨头坏死疾病方面特异性与敏感性较强，图像显示清晰。

Objective:To explore the clinical value of MRI in the diagnosis of avascular necrosis of the femoral head.Methods:153patients with avascular necrosis of the femoral head were selected,to conduct a comprehensive analysis of the medical image.Results:A total of 189 lesions occurred in the femoral head.There were 25 in stage 0,63 in stageⅠ,26 in stageⅡ 26,39 in stageⅢ～Ⅳ.The articular surface collapse,abnormal bone destruction,joint space becomes small.Conclusion:MRI in the diagnosis ofischemic necrosis of the femoral head disease specificity and sensitivity is strong,clear image display.
