To determine the normal range of aortic and pulmonary artery diameters on chest CT, and to search a constant ratio when the diameters of thoracic vascular structures are compared with an internal reference.
Contrast-enhanced chest CT scans of 133 pediatric patients were retrospectively evaluated. Diameters of ascending and descending aorta, main pulmonary artery, right and left pulmonary arteries and a constant thoracic vertebra were measured. The mean ratios of thoracic vascular diameters to the diameter of the thoracic vertebra were calculated.
There was a positive correlation between the age of the patients and vascular diameters. The mean ratios of vascular diameters to the diameter of thoracic vertebra, ranged from 1.1 for the ascending aorta to 0.70 for the right and left pulmonary arteries, were consistent.
Diameters of thoracic vascular structures increase with age. The consistent vertebral to vessel ratios can be useful in evaluation of chest CT of pediatric patients.
确定胸部CT上主动脉和肺动脉直径的正常范围，并寻找胸部血管结构直径与内部参考值比较时的恒定比例。
回顾性评估133例儿科患者的增强胸部CT扫描。测量升主动脉和降主动脉、主肺动脉、左右肺动脉以及一个恒定胸椎的直径。计算胸部血管直径与胸椎直径的平均比例。
患者年龄与血管直径呈正相关。血管直径与胸椎直径的平均比例一致，范围从升主动脉的1.1到左右肺动脉的0.70。
胸部血管结构的直径随年龄增长。一致的椎体与血管比例可用于儿科患者胸部CT的评估。
