Rare earth and barium fluorochloride screen-film combinations of different relative speeds were compared to conventional calcium tungstate systems in patients undergoing excretory urography under controlled conditions. Radiographs were ranked by subjective impressions of detail, contrast, mottle, motion unsharpness, overall quality, and acceptablility. Compared to a medium speed calcium tungstate screen/film combination (assigned a speed of 1), screen-film systems in the 2-5 speed range offered improvement in overall quality due to diminished respiratory motion unsharpness at the cost of some loss of detail and increase in mottle. Other advantages and disadvantages of fast screen-film systems are discussed.
在可控条件下，对接受排泄性尿路造影的患者，将不同相对速度的稀土和钡氟氯化物增感屏 - 胶片组合与传统的钨酸钙系统进行了比较。根据对细节、对比度、斑点、运动模糊、整体质量和可接受性的主观印象对射线照片进行排名。与中速钨酸钙增感屏/胶片组合（速度设定为1）相比，速度在2 - 5范围内的增感屏 - 胶片系统整体质量有所提高，这是因为呼吸运动模糊减少，但代价是细节有所损失且斑点增加。文中还讨论了快速增感屏 - 胶片系统的其他优缺点。
