摘　　要：目的构建特发性肺动脉瘤3D打印模型,并对构建模型的准确性进行评估。方法收集1例特发性肺动脉瘤患者的CT影像资料,用医学影像控制系统Mimics Research、3-Matic Research软件建立3D肺动脉瘤模型(3D模型),并对其进行优化(优化模型),将优化模型输入3D打印机构建肺动脉瘤3D打印模型(3D打印模型)。采用线性拟合回归分析、Bland-Altman分析法评价3D打印模型的准确性。结果构建并打印出肺动脉瘤3D打印模型(肺动脉瘤直径为55.38 mm)。测量CT模型与优化模型、优化模型与3D打印模型所得到两组测量值相关性强(r=0.99),且一致性强。结论成功构建特发性肺动脉瘤3D打印模型,且构建模型的准确性高。Objective To build a 3D printing model of idiopathic pulmonary aneurysm and to evaluate the accuracy of the model.Methods We collected the CT image data of the patient with the idiopathic pulmonary aneurysm,and used the medical image control system Mimics Research and 3-Matic Research software to build the 3D pulmonary aneu⁃rysm model(3D model),and optimized it(optimization model),and then input the optimization model into the 3D printer to build the 3D printing model of pulmonary aneurysm(3D printing model).Next,we used linear fitting regression method and Bland-Altman analysis method to evaluate the accuracy of 3D printing model.Results We got the 3D printing idio⁃pathic pulmonary aneurysm model successfully(the diameter of pulmonary aneurysm=55.38mm).The two groups of mea⁃sured values from the CT model and the optimization model,the optimization model and the 3D printing model had strong correlation(r=0.99)and consistency.Conclusion We have successfully constructed a 3D printing model of idiopathic pulmonary aneurysm and the 3D model has high accuracy.
