30 patients with known or suspected pulmonary nodules were examined using a digital image intensifier radiography system, a conventional radiography system and a tomography of the whole lung. 73.8% of the pulmonary nodules detected with tomography were also detected with the digital system, 69.1% with the conventional system. There was no significant difference between the two systems comparing false positive and false negative diagnoses. Regarding the dose reduction to nearly 25% of that of a conventional examination the digital technique should be preferred to the conventional technique, if pulmonary nodules are suspected.
对30例已知或疑似肺结节患者，使用数字影像增强X线摄影系统、传统X线摄影系统和全肺断层扫描进行检查。通过断层扫描检测出的肺结节中，73.8%也能被数字系统检测到，69.1%能被传统系统检测到。在比较假阳性和假阴性诊断方面，两种系统之间没有显著差异。如果怀疑有肺结节，考虑到剂量可降低至传统检查剂量的近25%，数字技术应优于传统技术。
