A computed radiographic system for generating digital film images was evaluated in the performance of excretory urography. Three experienced radiologists reviewed digital and conventional screen-film urograms for 100 patients in a prospective study to evaluate the clinical utility of the digital system. Results indicate no difference between digital and screen-film urograms in diagnostic sensitivity, specificity, or receiver-operating-characteristic curves for differentiating normal from abnormal studies. Readers' performances in making specific diagnoses were also the same with both techniques.
在排泄性尿路造影检查中，对一种用于生成数字胶片图像的计算机放射成像系统进行了性能评估。在一项前瞻性研究中，三位经验丰富的放射科医生对100例患者的数字尿路造影和传统屏-片尿路造影进行了评估，以评价数字系统的临床实用性。结果表明，在区分正常与异常检查的诊断敏感性、特异性或接受者操作特征曲线方面，数字尿路造影和屏-片尿路造影之间没有差异。两种技术在做出具体诊断时，阅片者的表现也相同。
