%X 摘要：目的 基于计算机辅助比较支气管自动测量及手动测量的优劣。方法 回顾性收集“数字肺”数据库中心自2015年6月至2015年8月在西安交通大学第一附属医院行肺癌筛查的体检人群19例。采用手动、计算机辅助的半自动和计算机自动测量支气管内径及外径。比较3种方法测量结果的一致性。结果 自动测量与半自动测量相关性最高(内径r=0.993，外径r=0.991)，其次是半自动测量与手动测量(内径r=0.992，外径r=0.985)，最后是自动测量与手动测量(内径r=0.979，外径r=0.980)。自动测量、半自动测量及手动测量对内径(r=0.992，r=0.993，r=0.991)和外径(r=0.990，r=0.994，r=0.992)的测量重复一致性较好。结论 自动测量与半自动测量的一致性最好，手动测量与前两者的相关性较好。<br>ABSTRACT: Objective To compare the advantages and disadvantages of bronchus manual measurement and automatic measurement based on computer aided method. Methods We retrospectively selected 19 cases for lung cancer screening in The First Affiliated Hospital of Xi’an Jiaotong University from June 2015 to August 2015 from the Digital Lung Database Center. Then we analyzed the consistence of inner and outer diameters of the bronchus by manual measurement, computer-aided semi-automatic measurement, and automatic measurement. Results Automatic measurement had the highest correlation with semi-automatic measurement (inner diameter r=0.993, outer diameter r=0.991), followed by semi-automatic measurement and manual measurement (inner diameter r=0.992, outer diameter r=0.985), and automatic measurement and manual measurement (inner diameter r=0.979, and outer diameter r=0.980). Automatic measurement, semi-automatic measurement had good consistency of repetition measurement for inner diameter (r=0.992, r=0.993, r=0.991) and outer diameter (r=0.990, r=0.994, r=0.992). Conclusion The consistency between automatic measurement and computer-aided semi-automatic measurement is the highest, and the consistency between manual measurement and the other two methods is good
