摘　　要：随机选取９０患者，同一天摄取高、低电压胸片各一张。具有可比性的共８６对。用以表达肺部细微结构显示量为核心的胸部Ｘ线评价表（解剖标志／物理参数评价表），对８６对高、低电压胸片进行逐项品评。高电压胸片上气管、肺部细微结构、胸膜、胸椎及心脏重叠区的影像显示均有改善，以气管、心脏重叠区的影像显示提高最大。高电压（ＨＫＶ）平均总得分较低电压（ＬＫＶ）胸片总得分提高４１．２％。高电压胸部摄影技术在尘肺诊断中应用有巨大潜能。Ninety pairs of postteroanterior chest radiograph were taken by both high and low KV technique and were ran-domly performed on the same day during a routine pneumoconiosis survey。 86 pairs of them were technique quality comparable, The l 72 radiographs were scored according to the assessment schedule of anatomlc landmarks/physical pa-rameters in a random sequence, The results indicated that the high KV radiographs scored more than low ones in tra-chea, pulmonary small structure, diaphragm outline, spine and retrocardia area。 The score of trachea and retrocardia area increased most markedly.The total score of high KV radiographs increased by 41.2%as compared with that of low ones, The high KV radiography may have great potentiality for diagnosis in pneumoconiosls。
