摘要： 目的 运用薄层CT扫描并多平面重组（multiplanar reconstruction，MPR）及容积再现（volume reconstruction，VR）技术探讨青少年锁骨胸骨端骨骺发育CT分级方法。 方法 通过薄层CT冠状面、横断面扫描以及MPR、VR技术观察我国华东、华南地区460名15～25周岁男、女性青少年双侧锁骨胸骨端发育影像特征，测量并计算双侧锁骨胸骨端骨骺最长径、干骺端最长径、骨骺最长径与干骺端最长径比值、骨骺面积、干骺端面积以及骨骺面积与干骺端面积比值，建立锁骨胸骨端骨骺发育CT分级方法。 结果 在Schmeling分级的基础上，融合锁骨胸骨端CT图像重组信息，将锁骨胸骨端骨骺发育过程分为1～5级，其中2级和3级分别包括a、b、c 3个亚级。 结论 应用于本分级的样本量大、年龄范围宽、可操作性强，利用CT图像重组技术，分析与青少年锁骨胸骨端骨骺发育密切相关的数据，增加了本分级方法的可行性。

Abstract: Objective To establish a CT staging method of sternal end of clavicle epiphyseal growth for teenagers by thin layer CT scan, multiplanar reconstruction （MPR） and volume reconstruction （VR） technologies. Methods The CT imaging characteristics, which collected from 460 teenagers （aged from 15 to 25） in East and South China, were studied through both sternal ends of clavicles’ imagings by thin layer coronal CT scan and axial CT scan, MPR and VR technologies. The parameters of sternal end of clavicle including the longest diameter of epiphysis, the longest diameter of metaphysis, their length ratio, area of epiphysis, area of metaphysis, and their area ratio were measured and calculated in order to establish new classification. Results Based on the staging method of Schmeling, integrating the CT imaging reconstruction information of sternal end of clavicle, the new classification of sternal end of clavicle epiphyseal growth were divided into 1 to 5 stages, and stage 2 and stage 3, respectively, contained a, b and c sub-classification. Conclusion This new classification has merits of large sample size, wide age range and easy operability. By using CT imaging reconstruction techniques and analyzing the data which closely related to sternal end of clavicle epiphyseal growth of teenagers, the feasibility of the staging method could be increased.
