The width of the right paratracheal stripe (RPS) has been established in normal adults but not in normal children. The thymus and great vessels are relatively larger in children than in adults and could obscure or widen the RPS. We found that obscuration does occur and, therefore, the RPS is less often measurable in children than in adults. Widening by the thymus and great vessels, however, does not occur. The width of the RPS in normal children, 0.5 to 3.0 mm, is slightly less than in adults. From this study of normal children and our subsequent experience with pediatric patients, we conclude that in a child an RPS 4 mm or wider is reliable evidence of disease affecting the trachea, mediastinum, or pleura.
正常成年人气管旁右侧条纹（RPS）的宽度已明确，但正常儿童的尚未明确。儿童的胸腺和大血管相对比成年人的大，可能会使RPS模糊或变宽。我们发现模糊确实会出现，因此，与成年人相比，儿童中RPS更不易测量。然而，胸腺和大血管不会使其变宽。正常儿童的RPS宽度为0.5至3.0毫米，略小于成年人。通过对正常儿童的这项研究以及我们随后对儿科患者的经验，我们得出结论，在儿童中，RPS宽度达到或超过4毫米是影响气管、纵隔或胸膜疾病的可靠证据。
