为了尽可能缩小早期矽肺在X线与病理表现上的差距,不少同行在X线方法上作了改进和试探。本文抱着同样目的,采用普通摄影、高电压摄影以及华氏(Valsalva)摄影三种方法进行检查,通过对比,比较它们在矽肺早期诊断上的作用以及各自的优缺点。同时,把普通大胸片、华氏大胸片与相应的100×100毫米大胸缩片作对照,观察100×100毫米片在早期矽肺诊断上的作用。
In order to minimize the gap between the early silicosis and pathological manifestations of silicosis, many colleagues made improvements and tests on the X-ray method. This article for the same purpose, using ordinary photography, high voltage photography and Valsalva photography three ways to check, compared by comparing their role in the early diagnosis of silicosis and their respective advantages and disadvantages. At the same time, the common large chest X-ray, large chest X-ray film and the corresponding 100 × 100 mm chest X-ray contrast for the observation of 100 × 100 mm film in the early diagnosis of silicosis.
