It is practical value for determination the teenagers whether the age is full of the legal responsibility age of 18 years old or not by estimating skeletal age of sternal end of clavicle. The traditional methods mainly based on X-ray radiography. However, sternal end of clavicle and adjacent lung, bronchus, sternum, rib, transverse process of thoracic vertebra are overlapped each other. As a result of overlapping, there will be obtained false negative or positive film reading results when according to X-ray observation of epiphyseal growth of sternal end of clavicle, which directly affect the scientificalness and accuracy of estimating of skeletal age. In recent years, the scholars at home and abroad have started to use thin layer CT scan technology to estimate skeletal age of the sternal end of clavicle. With the 2D and 3D CT recombination technology, the accuracy of the film reading distinctly improves by making the shape, size and position of epiphysis displayed clearly. This article reviews the application and research progress of thin layer CT scanning technology in estimating skeletal age of sternal end of clavicle at home and abroad, analyzes the superiority and value of thin layer CT scan technology, which applied to skeletal age of sternal end of clavicle.
通过评估锁骨胸骨端的骨骼年龄来确定青少年是否已满18岁这一法定责任年龄具有实际价值。传统方法主要基于X线摄影。然而，锁骨胸骨端与相邻的肺、支气管、胸骨、肋骨、胸椎横突相互重叠。由于重叠，根据X线观察锁骨胸骨端骨骺生长情况时，会出现假阴性或假阳性的读片结果，这直接影响骨骼年龄估计的科学性和准确性。近年来，国内外学者开始使用薄层CT扫描技术来评估锁骨胸骨端的骨骼年龄。借助二维和三维CT重组技术，通过清晰显示骨骺的形状、大小和位置，读片的准确性明显提高。本文综述了薄层CT扫描技术在国内外评估锁骨胸骨端骨骼年龄中的应用及研究进展，分析了薄层CT扫描技术应用于锁骨胸骨端骨骼年龄的优势和价值。
