Abstract：Objective To investigate the difference of CT-enhanced histogram between pulmonary sclerosing pneumocytoma and hamartoma in order to improve the diagnosis.Methods The data of patients with pulmonary sclerosing pneumocytoma and hamartoma confirmed by surgery and pathology were analyzed retrospectively.The gender,age,CT signs of the two groups were recorded and analyzed and the region of interest in arterial phase and venous phase were delineated respectively using 3D Slicer software,and the first-order histogram features were analyzed by use of radiomics.The differences of general clinical,CT signs and histogram features between the two groups were compared.Results There were 13 cases of pulmonary sclerosing pneumocytoma and 23 cases of hamartoma.There was no statistical difference in age,sex,distribution of lung lobes,size,lobu-lation sign,vascular convergence sign,and vascular edge sign between the two groups.There was significant difference between the two groups in enhanced CT arteriovenous phase.Histogram parameters showed that 10 percentile of arterial phase and 90 per-centile,mean,median and total energy of arteriovenous phase were significantly different between the two groups(P<0.05).Conclusion Based on CT enhancement,some first-order histogram features have statistical significance between pulmonary sclerosing pneumocytoma and hamartoma,which can provide quantitative reference for diagnosis.
