X-ray examinations represent a variety of indications with different demands on exposure latitude, spatial and contrast resolution of screen-film-system combinations in paediatric radiography. The value of digital luminescent radiography (DLR) was compared to conventional x-ray examinations carried out with screen-film-systems, speed class 200, by analysing matched digital and conventional exposures in 200 abdominal, 600 skeletal and 300 chest examinations. The exposure of DLR was reduced to 50% of conventional exposure. Analysing the results in abdominal and skeletal radiography, DLR proved to be diagnostically equivalent to conventional radiography despite the reduction in exposure dose. DLR of the newborn chest compared to conventional x-ray studies was not always sufficient due to lower digital spatial resolution.
在儿科放射学中，X射线检查呈现出各种不同的适应症，对屏-片系统组合的曝光宽容度、空间分辨率和对比度分辨率有不同要求。通过分析200例腹部、600例骨骼和300例胸部检查中匹配的数字和传统曝光情况，将数字荧光X线摄影（DLR）的价值与使用速度等级为200的屏-片系统进行的传统X射线检查进行了比较。DLR的曝光量减少到传统曝光量的50%。分析腹部和骨骼放射摄影的结果，尽管曝光剂量降低，但DLR在诊断上被证明与传统放射摄影相当。由于数字空间分辨率较低，新生儿胸部的DLR与传统X射线研究相比并不总是足够的。
