摘　　要：目的探讨基于CT增强硬化性肺泡细胞瘤(PSP)与错构瘤直方图差异,以便提高诊断率。方法选取经手术病理证实、行CT增强检查的PSP及错构瘤患者资料。记录、分析两组病例的性别、年龄、CT影像征象等,并采用3D Slicer软件于动脉期、静脉期分别勾画感兴趣区,使用Radiomics分析一阶直方图特征,比较两组间一般临床、CT征象、直方图特征的差异。结果PSP患者13例(PSP组)、错构瘤23例(错构瘤组),两组间在年龄、性别、肺叶分布、大小、分叶征、血管集束征、血管贴边征比较差异无统计学意义(P>0.05);两组在CT增强动、静脉期差异有统计学意义(P<0.05)。直方图参数特征显示动脉期第十百分位及动、静脉期第九十百分位、均数、中值、总能量在两组间的差异有统计学意义(P<0.05)。结论基于CT增强、部分一阶直方图特征在PSP与错构瘤两者间差异有统计学意义(P<0.05),可为诊断提供定量参考价值。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,lobulation 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 percentile,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.
