Abstract:
Objective To explore the value of computer-aided measurement of the mass-based consolidation-to-tumor ratio(CTRmass)in predicting preoperative clinical stage IA lung adenocarcinoma invasion.Methods A total of 56 patients with stage IA lung adenocarcinoma were retrospectively selected from Linfen Central Hospital and the National Lung Screening Trial(NLST)database(project number NLST-1053),and all of them were confirmed by pathology.Computer-aided software was used to automatically cal-culate parameters such as the volume-based consolidation-to-tumor ratio(CTRvol),CTRmass,average CT value,and maximum axial diameter,and its correlation with pathological results was analyzed.Results When the CTRmass≥30.95％,it indicated that lung nodules were more likely to be invasive adenocarcinoma(IAC).Conclusion CTRmass,based on computer-aided software measure-ment,can be used as one of the important indicators to evaluate the preoperative invasion of clinical stage IA lung adenocarcinoma,guiding the selection of surgical methods,and obtaining better curative effects.
