应用ＳＭＣ－５型单探测头彩色记录扫描仪联接２８６计算机处理图像，以１１３锡（Ｓｎ）－１１３ｍ铟（Ｉｎ）发生器制备１１３ｍＩｎ胶体，用５％碳酸氢钠调节ｐＨ至６．４，以此检测了急性阻塞性呼吸道疾病（ＡＯＰＤ），包括在Ｘ线胸片上呈现弥漫性肺容量增加的患儿２２６例、肺容量不增加的患儿５７例，另以同样检测条件检测了正常健康儿１９例。结果发现合并胃食道返流（ＧＥＲ）的阳性率分别为３３．６３％、１７．５４％和５．２６％，经统计学处理后提示弥漫性肺容量增加组合并ＧＥＲ显著高于肺容量不增加组和正常健康儿组，同时详细研讨其发病机理。认为ＡＯＰＤ的严重程度同ＧＥＲ的发病呈正相关关系，临床上应引以重视。
The images were processed using a SMC-5 single-probe color-recording scanner with a computerized image processing system to prepare 113mIn colloids using a 113 tin (Sn) -113m indium (In) generator. The pH was adjusted to 6.4 with 5% sodium bicarbonate This test detects acute obstructive airways disease (AOPD), including the X-ray showed diffuse lung capacity increased in 226 cases of children without increased lung capacity in 57 cases of children with the same test conditions were detected in normal healthy children 19 cases. The results showed that the positive rates of gastroesophageal reflux (GER) were 33.63%, 17.54% and 5.26%, respectively. After statistical analysis, it was suggested that the diffuse lung volume increased and the GER was significantly higher than the lung volume Increase the group and normal healthy children, at the same time to study its pathogenesis in detail. AOPD that the severity of the incidence of GER was positively correlated with the clinical should be taken seriously.
