The authors stress the difficulty of detecting pleural thickenings due to asbestos by radiography, before the late stage when calcification appears. Using Mackenzie and Harries's technique, they radiographed 64 subjects working in the naval shipbuilding yard in Nantes, who had previously been examined by radiophotography. Their results confirmed the superiority of the 45 degrees oblique incidence for demonstrating patches of pleural thickening in those areas where they occur most frequently. The value of this early detection is purely social and occupational at the present time, as it cannot be used to give a prognosis as to the possible appearance of a more serious lesion such as mesotheliomas.
作者强调，在出现钙化的晚期之前，通过射线照相术检测因石棉导致的胸膜增厚存在困难。他们采用麦肯齐和哈里斯的技术，对64名在南特海军造船厂工作的人员进行了射线照相，这些人员此前已接受过放射摄影检查。他们的结果证实，45度斜入射在显示胸膜增厚斑块方面具有优越性，这些斑块最常出现在某些区域。目前，这种早期检测的价值纯粹是社会和职业方面的，因为它不能用于预测更严重病变（如间皮瘤）可能出现的情况。
