骨龄能够较客观地反映儿童及青少年生长发育水平，还可以预测生长潜力，在临床医学、法医学、体育学等领域具有重要作用。手腕部及锁骨胸骨端是骨龄评估最常用的部位。骨龄的成像不仅有X线平片，还有超声、CT及磁共振成像。骨龄的评估方法由传统人工到自动化评估，准确性及效率不断提高。现主要对手腕部及锁骨胸骨端骨龄评估的技术及方法研究进展进行综述。 Bone age is an important index objectively reflecting the growth and development level of children and adolescents， as well as predicting growth potential。It plays a key role in various complicated situations involving clinical medicine， forensic and sports science。The wrist and the extremitas sternalis of clavicle are the most common sites for bone age assessment。Several techniques are available to evaluate bone age， including X-ray plain radiography， ultrasound， CT and magnetic resonance imaging。The accuracy and efficiency of bone age assessment have been continuously improved from traditional manual assessment to automatic assessment。This paper mainly reviews the advances in the techniques and methods for bone age assessment of the wrist and the extremitas sternalis of clavicle。
