To compare selenium- versus phosphor-based digital chest imaging for visualization of various anatomic regions of the chest.
Thirteen observers analyzed pairs of posteroanterior (PA) and lateral chest radiographs of 63 patients. One radiograph in each pair was obtained with a digital selenium chest radiography system, and the other with a storage phosphor-based technique. Each observer rated the visibility and the radiographic quality of 21 anatomic regions.
The observers rated visualization obtained with the selenium system as better than that obtained with the storage phosphor system in 12 anatomic regions (right lower lobe, retrodiaphragmatic, upper lobes, minor fissure, hilum, carina, azygoesophageal recess, ribs, soft tissue, upper mediastinum on the PA image, and major fissure and sternum on the lateral image). Five regions were equally appreciated (retrocardiac on the PA, lower lobes, lingual-middle lobe, soft tissue, and subdiaphragmatic region on lateral images). Four regions were rated better on phosphor imaging than on selenium films (thoracic spine on PA, upper lobes, lower, and upper thoracic spine on lateral films) (17,199 observations, P < 0.05, sign test).
On PA images the digital selenium chest system provides better visualization of most anatomic structures than the phosphor system. Lateral images show an almost equal preference.
比较基于硒和基于磷的数字胸部成像在胸部各解剖区域可视化方面的效果。
13名观察者分析了63例患者的后前位（PA）和侧位胸部X线片。每对X线片中的一张是用数字硒化胸部X线摄影系统获得的，另一张是用存储磷光技术获得的。每位观察者对21个解剖区域的可视性和X线片质量进行评分。
观察者认为，在12个解剖区域（右下叶、膈后、上叶、小裂、肺门、隆突、奇静脉食管隐窝、肋骨、软组织、PA图像上的上纵隔，以及侧位图像上的大裂和胸骨），硒系统获得的可视化效果优于存储磷光系统。5个区域的评价相同（PA图像上的心后区、下叶、舌叶-中叶、软组织，以及侧位图像上的膈下区域）。4个区域在磷光成像上的评分高于硒化胶片（PA图像上的胸椎、上叶，以及侧位胶片上的下胸椎和上胸椎）（17,199次观察，P < 0.05，符号检验）。
在PA图像上，数字硒化胸部系统对大多数解剖结构提供了比磷光系统更好的可视化效果。侧位图像显示出几乎相同的偏好。
