薄层CT扫描技术在锁骨胸骨端骨龄评估中的应用进展

Progress in Thin Layer CT Scan Technology in Estimating Skeletal Age of Sternal End of Clavicle

评估锁骨胸骨端骨龄对于推断青少年是否已满18周岁法定责任年龄具有实用价值,传统的研究方法主要基于X线检查,但由于锁骨胸骨端与相邻的肺、支气管、胸骨、肋骨及胸椎横突等解剖结构相互重叠,通过X线观察锁骨胸骨端骨骺发育时,较易出现假阴性或假阳性的阅片结果,直接影响骨龄鉴定意见的科学性与准确性。近年来,国内外已有学者运用薄层CT扫描技术评估锁骨胸骨端骨龄,并通过联合CT二维、三维图像重组技术,使骨骺形状、大小及位置得以清晰显示,提高了结果的准确性。据此,本文综述了国内外关于薄层CT扫描技术在锁骨胸骨端骨龄评估中的应用及研究进展,分析薄层CT扫描技术运用于锁骨胸骨端骨龄研究的优势以及价值所在。

It is practical value sponsibility age of 18 years old tional methods mainly based on for determination the teenagers whether the age is full of the legal re- or not by estimating skeletal age of sternal end of clavicle. The tradi- 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 scientifical- ness 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.
