摘　　要：目的探讨数字X线摄影(DR)调节控制超短时间曝光在婴幼儿胸部摄影中的应用价值。方法随机抽取我院DR调节控制及固定控制的婴幼儿胸片各100例,由放射科中级以上医技师各2名对所有胸部X线片质量进行分析,分别统计甲、乙、丙及废片率,同时对婴幼儿胸部的细微结构显示率进行评价。结果DR调节控制婴幼儿胸部影像:甲片率70%,乙片率20%,丙片率10%,废片率0%;DR固定控制婴幼儿胸部影像:甲片率42%,乙片率48%,丙片率27%,废片率2%。婴幼儿肺内的细微结构显示率:DR调节控制影像为100%,DR固定控制影像为90%。结论DR调节控制的婴幼儿胸部影像的诊断图像质量明显好于DR固定控制影像,有利于放射诊断。Objective To explore the applied value of the super - short exposure time of the DR adjustable control in radiography of infant chest. Methods 100 chest radiographic films of infant in adjustable control group and fixed control group respectively were selected randomly. The quality of all films was evaluated by 4 technicians in charge in 4 grades （ A, B, C and waste ） and the detective rate of the tiny parts of the images was also evaluated. Results DR adjustable control：the rate of grade A,B,C and waste was 70% ,20% , 10% and 0% respectively. DR fixed control：the rate of grade A, B, C and waste was 42% ,41% , 15% and 2% respectively. The detective rate of tiny parts was 100% and 90% in DR adjustable control group and DR fixed control group respectively. Conclusion DR adjustable control chest film in infant is better than DR fixed control in image quality. DR adjustable control system is good for radiographic diagnosis.
