The authors report a double study comparing the conventional chest radiograph and digitalised images. The first study was to visualise normal mediastinal structures (the contour of the posterior mediastinum, the azygo-oesophageal recess, the bronchial sub-segments, intermediate, carina, trachea) and showed a superiority of the digitalised image. The second study was on the recognition of radiological abnormalities in lung cancer which showed no precise superiority of the digitalised image in the mediastinum (bronchial tumour, adenopathies) and a current deficiency at the pleuro-parenchymal level (pulmonary nodules, atelectasis pleural effusion). This double study presents parallel results to those obtained by the anglosaxon authors on different prototypes in whom the technology and possibilities were different. The principles, the advantages and the limits of these prototypes were described and in conclusion a chosen technique for the medium term is proposed by the authors.
作者报告了一项比较传统胸部X光片和数字化图像的双重研究。第一项研究旨在观察正常纵隔结构（后纵隔轮廓、奇静脉食管隐窝、支气管亚段、中间段、隆突、气管），结果显示数字化图像具有优势。第二项研究是关于肺癌放射学异常的识别，结果表明数字化图像在纵隔（支气管肿瘤、淋巴结肿大）方面没有确切优势，在胸膜-实质层面（肺结节、肺不张、胸腔积液）目前存在不足。这项双重研究的结果与盎格鲁撒克逊作者在不同原型上获得的结果相似，这些原型的技术和可能性各不相同。文中描述了这些原型的原理、优点和局限性，最后作者提出了中期的首选技术。
