Normal thoracic aortic dimensions in adults have been established by means of computed tomography (CT), but such measurements are not available in children. To establish normal standards, contrast material-enhanced chest CT scans of 117 children and adolescents, ranging in age from 2 weeks to 19 years, were reviewed retrospectively. Patients with congenital heart disease, vascular anomalies, renal disease, hypertension, and connective-tissue disorders were excluded, resulting in 97 studies. Diameters of the thoracic aortas were measured at three levels. Interobserver and intraobserver variances were determined. A direct linear relationship to patient age was observed, and regression analysis was performed. These standards help in differentiating the normal from the abnormal aorta on chest CT scans of children.
成人正常胸主动脉尺寸已通过计算机断层扫描（CT）确定，但儿童尚无此类测量数据。为建立正常标准，对117名年龄在2周至19岁的儿童和青少年的对比剂增强胸部CT扫描进行了回顾性分析。排除患有先天性心脏病、血管异常、肾病、高血压和结缔组织疾病的患者，最终纳入97项研究。在三个层面测量胸主动脉直径。确定了观察者间和观察者内的差异。观察到与患者年龄呈直接线性关系，并进行了回归分析。这些标准有助于在儿童胸部CT扫描中区分正常与异常主动脉。
