摘要
背景：肺移植后患者床边胸片的质量关系到对肺部病变的评价,对临床具有十分重要的价值。目的：比较肺移植后患者应用传统屏-片组合和计算机数字化系统进行床边胸部摄片的图像质量,以选择优良方案。方法：回顾性分析南京医科大学附属无锡市人民医院78例肺移植后患者床边胸片传统屏-片摄影425张和计算机数字化摄影411张的图像资料,提出优质片评估标准,经3位高年资医师、技师读片将其从优质片到废片分为Ⅰ~Ⅳ级,然后分析影响两组床边胸片质量的因素,并计算两组的平均曝光剂量。结果与结论：肺移植后患者床边胸片,传统屏-片组：Ⅰ级片135张（31.8%）、Ⅱ级片171张（40.2%）、Ⅲ级片107张（25.2%）、Ⅳ级片12张（2.8%）;计算机数字化摄影组：Ⅰ级片266张（64.7%）、Ⅱ级片105张（25.5%）、Ⅲ级片37张（9.0%）、Ⅳ级片3张（0.7%）,两组床边胸片图像质量分级差异有非常显著性意义（P〈0.01）。计算机数字化摄影组平均曝光剂量1.56mA·s明显小于屏-片组3.27mA·s（P〈0.01）。提示肺移植后患者计算机数字化摄影系统床边胸片质量明显优于传统屏-片组合床边胸片,应用计算机数字化摄影系统可提高优质片,减少废片,降低X射线照射剂量,可作为肺移植后患者床边胸片的首选。
BACKGROUND：Quality of beside chest radiography is very important for lesion assessment after lung transplantation. OBJECTIVE：To compare the quality of bedside chest radiography based on screen piece combination （TP） and computed radiography system （CR） after lung transplantation, and to select a better plan. METHODS：A retrospective analysis of 425 TP and 411 CR bedside chest images from 78 patients after lung transplantation admitted in Wuxi People’s Hospital Affiliated to Nanjing Medical University were conducted. All the images were classified into Ⅰ-Ⅳ levels by three high qualification physicians and technicians to analyze the influential factors related to quality of bedside chest radiographs in the two groups and calculate average exposure dosages. RESULTS AND CONCLUSION：In the TP group, there were 135 （31.8%） for level Ⅰ, 171 （40.2%） for level Ⅱ, 107 （25.2%） for level Ⅲ, and 12 （2.8%） for level Ⅳ. In the CR group, there were 266 （64.7%） for level Ⅰ, 105 （25.5%） for level Ⅱ, 37 （9.0%） for level Ⅲ, and 3 （0.7%） for level Ⅳ.There was a significant difference between the two groups （P 0.01）. The average exposure dosage was 1.56 mAs in the CR group, significantly lower than that in the TP group （3.27 mAs） （P 0.01）. These findings show that CR can improve the quality of bedside chest radiography, and decrease the average exposure dose
