PURPOSE
To test the clinical usefulness of computed radiography (CR) with a storage phosphor plate in upper gastrointestinal radiographic examinations, a newly devised phantom gastric mucosa was used.
MATERIAL AND METHODS
Simulated small elevated and depressed lesions were created on a phantom gastric mucosa made from a styrofoam "plate". Twenty-four sets of each CR and screen-film radiographs (SR) were obtained using phototimed exposures. Receiver operating characteristic (ROC) study and visual ranking using these images were performed.
RESULTS
There was no significant difference between the ROC curves of CR and SR. By visual ranking, CR was equal to or better than SR in most cases. In no case was SR definitely superior to CR.
CONCLUSION
CR can be safely applied to upper gastrointestinal roentgenologic examinations.
目的
为测试在胃上部X线造影检查中使用存储磷光板的计算机X线摄影（CR）的临床实用性，使用了一种新设计的模拟胃黏膜模型。
材料与方法
在由聚苯乙烯泡沫塑料“板”制成的模拟胃黏膜模型上制作模拟的小隆起和凹陷病变。使用光控曝光获得24组CR图像和屏-片射线照片（SR）。使用这些图像进行了接受者操作特征（ROC）研究和视觉分级。
结果
CR和SR的ROC曲线之间无显著差异。通过视觉分级，在大多数情况下CR等于或优于SR。在任何情况下，SR都未明显优于CR。
结论
CR可安全应用于胃上部X线检查。
