摘　　要：目的 探讨基于磁共振成像(MRI)评估股骨头灌注指数、突出指数、受累程度与Perthes病分期的关系。方法 选取我院116例Perthes病患儿,初次就诊时均行MRI检查,评估股骨头灌注指数、突出指数、受累程度,分析其临床价值。结果 良好组改良Waldenstrom分期及突出指数、受累程度低于不良组,股骨头灌注指数高于不良组(P<0.05);Perthes病患儿改良Waldenstrom分期与股骨头灌注指数呈负相关,与突出指数、受累程度呈正相关(P<0.05);股骨头灌注指数、突出指数、受累程度预测Perthes病患儿预后不良的曲线下面积(AUC)分别为0.855、0.748、0.802,各指标联合预测的AUC最大,为0.963。结论 MRI检测股骨头灌注指数、突出指数、受累程度与Perthes病分期密切相关,且在预测患儿疾病转归方面具有较高应用价值。Objective To explore the relationship between Perthes disease stage and Perthes disease stage based on magnetic resonance imaging(MRI) assessment of femoral head perfusion index, prominent index, degree of involvement. Methods A total of 116 children with Perthes disease in our hospital were selected. MRI was performed at the first visit to evaluate the femoral head perfusion index, protrusion index, and degree of involvement, and analyze their clinical value. Results The modified Waldenstrom staging and protruding index, and the degree of involvement in the good group were lower than those in the poor group, and the femoral head perfusion index was higher than that in the poor group(P<0.05);the modified Waldenstrom staging of children with Perthes disease was negatively correlated with the femoral head perfusion index, and was negatively correlated with the protruding index The degree of involvement was positively correlated(P<0.05);the femoral head perfusion index, protrusion index, and the area under the curve(AUC) for predicting poor prognosis of children with Perthes disease were 0.855,0.748, and 0.802,respectively. The combination of each index predicted the largest AUC,Is 0.963. Conclusion MRI detection of femoral head perfusion index, prominent index,and degree of involvement are closely related to the staging of Perthes disease, and it has high application value in predicting the outcome of the disease in children.
