胸部X线平片是目前尘肺临床诊断的主要方法和依据,常见因胶片过小,肺野外带和胸膜病变不能充分反映而影响诊断。我们在尘肺检查中,随机对无胸廓畸形的195名男性(年龄为30～60岁,平均47.68岁;体重45～65.3kg,平均58.79kg;身高1.50～1.78m,平均1.65±0.051m,经检验,身高符合正态分布)用35×35cm胶片摄后前位胸片一张(焦—片距1.8m),测量胸廓横、纵径。同时测量分析既往用30.5×38.1cm胶片所照的胸片1719张;以探讨尘肺检查所需胶片的大小。 测量方法:横径为胸廓两侧肋骨外缘最宽点的水平连线(cm)。纵径为第一肋骨上缘至最低肋隔角的垂直线(cm)。按一侧或双侧未能包含肋骨外缘最凸点
Chest X-ray film is the main method of clinical diagnosis of pneumoconiosis and the basis of the common film is too small, lung field and pleural disease can not fully reflect the impact of the diagnosis. In our pneumoconiosis study, we randomly assigned 195 men without thoracic deformities (age 30-60 years, mean 47.68 years; weight 45-65.3 kg, average 58.79 kg; height 1.50-1.78 m, average 1.65 ± 0.051 m, Test, height in line with the normal distribution) with 35 × 35cm film after the first chest radiograph (coke - film distance 1.8m), measurement of thoracic transverse and longitudinal diameter. Simultaneous measurement and analysis of 1719 chest radiographs taken with 30.5 x 38.1 cm film was performed to investigate the size of the film required for pneumoconiosis examination. Measurement methods: horizontal diameter of the ribs on both sides of the outer edge of the widest horizontal connection (cm). The vertical diameter is the vertical line (cm) between the upper edge of the first rib and the lowest rib. One or both sides of the rib can not contain the most convex bumps
