目的：本研究旨在测试使用附加制造技术三维(3D)打印的可行性，以根据临床放射学研究创建个性化/患者特定的肝脏3D物理模型，用于外科住院医师教育。设计：将来自计算机断层扫描或磁共振成像扫描的患者特定的成像数据以数字成像和医学通信格式呈现并使用计算机软件进行处理，将医学成像数据集转换为用于3D打印的立体光刻格式的3D几何文件。商业第三方使用激光烧结尼龙来打印3D模型，这提供了以低成本获得昂贵的工业级高分辨率3D打印机的途径。结果：以每个模型不到100美元的成本打印了多个针对患者的门静脉和肝静脉解剖的术前3D物理模型。结论：目前的3D打印技术可以用于根据临床放射学研究创建低成本的个性化/患者特定的肝脏3D模型，用于外科住院医师的教学。(C)2014年，由Elsevier Inc.代表外科项目主任协会出版
OBJECTIVE: This study was used to test the feasibility of using additive fabrication techniques 3-dimensional (3D) printing to create personalized/patient-specific hepatic 3D physical models from clinical radiology studies for surgical resident education.DESIGN: Patient-specific imaging data from either computed tomography or magnetic resonance imaging scans, in Digital Imaging and Communications in Medicine format, were rendered and manipulated with computer software, translating the medical imaging data sets into useful 3D geometry files in stereo lithography format for 3D printing. A commercial third party was used to print the 3D models in laser sintered nylon, which provided access to expensive, industrial-grade, high-resolution 3-D printers at a low cost.RESULTS: Multiple patient-specific preoperative 3D physical models were printed of portal and hepatic venous anatomy at a cost of less than $100 per model.CONCLUSION: Current 3D printing techniques can be used to create low-cost personalized/patient-specific hepatic 3D models from clinical radiology studies for surgical resident education.
