Abstract: Objective To investigate the application value of quantitative analysis of the energy spectrum CT in the diagnosis and differential diagnosis of pulmonary mucinous adenocarcinoma and non-mucinous adenocarcinoma.Methods A retrospective analysis was conducted on the energy spectrum CT parameters of 12 cases of pulmonary mucinous adenocarcinoma and 24 cases of non-mucinous adenocarcinoma confirmed by surgery and pathology.Results There were significant differences between pulmonary mucinous adenocarcinoma and non-mucinous adenocarcinoma in 40-60 keV in plain scan,50-100 keV in arterial phase,40-140 keV CT value in venous phase and delayed phase,effective atomic number in plain scan,iodine concentration in venous phase and delayed phase(P<0.05).Conclusion The analysis of parameters of energy spectrum CT can be used for qualitative diagnosis and differential diagnosis of pulmonary mucinous adenocarcinoma and non-mucinous adenocarcinoma.
