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 semiautomatic measurement is the highest, and the consistency between manual measurement and the other two methods is good.
