Replacement of radiography by sonography for determination of skeletal maturity.
Sonographic and radiographic evaluation of the maturation of the iliac bone apophysis (Risser's sign) and evaluation of the distal radial epiphyses.
64 children and adolescents with idiopathic scoliosis, aged from 5 to 19 years.
Sonograms with corresponding radiographs were available for the hand and wrist in 36 cases and for the iliac bone in 28 cases. Comparison of sonographic with radiological data revealed sonography to have a sensitivity for qualifying the status of the distal radial epiphysis of 93.1%. Specificity was 100%, accuracy 94.4% for investigation of the distal radial epiphysis. Overall accuracy for correct determination of Risser's stage by ultrasound (in comparison with the radiographic standard) was 89.2%.
These findings suggest that ultrasound is a useful and highly acceptable tool for bone age determination in clinical routine or screening studies and will help to reduce ionizing radiation to children and adolescents.
用超声检查替代X线摄影来确定骨骼成熟度。
对髂骨骨骺（里塞尔征）成熟度进行超声和X线评估，并对桡骨远端骨骺进行评估。
64例5至19岁的特发性脊柱侧弯儿童及青少年。
36例患者有手部和腕部的超声图像及相应X线片，28例患者有髂骨的超声图像及相应X线片。超声检查与放射学数据比较显示，超声检查对判定桡骨远端骨骺状态的敏感度为93.1%。特异性为100%，对桡骨远端骨骺检查的准确率为94.4%。通过超声正确判定里塞尔分期（与X线摄影标准相比）的总体准确率为89.2%。
这些研究结果表明，超声是临床常规或筛查研究中确定骨龄的一种有用且高度可接受的工具，将有助于减少儿童及青少年所接受的电离辐射。
