Computed radiography has proved useful as a localization device for computed tomography. In an attempt to evaluate computed radiography as a primary diagnostic device, 16 patients were evaluated with various degrees of gallbladder opacification following standard oral cholecystograms, and 15 patients were evaluated with renal masses, identified on standard excretory urography. Subjective evaluation of computed radiographs as compared to the standard radiographs demonstrated no diagnostic advantage to computed radiography. The poor spatial resolution of the computed radiographs was not overcome by the improvement in contrast resolution.
计算机X线摄影已被证明作为计算机断层扫描的定位设备是有用的。为了评估计算机X线摄影作为一种主要诊断设备的性能，对16例在标准口服胆囊造影后胆囊呈现不同程度显影的患者进行了评估，并对15例在标准排泄性尿路造影中发现有肾肿块的患者进行了评估。与标准X线片相比，对计算机X线片的主观评估表明计算机X线摄影没有诊断优势。计算机X线片较差的空间分辨率并未因对比度分辨率的提高而得到克服。
