They used DICOM data from a MR angiogram without contrast using free software (OsiriX Lite, ), which allows for easy export of Standard Tesselation Language (STL) into commercial graphic design software (Autodesk 3D Studio Max) to remove noise and smooth the surface of the model to increase its visual appeal. The authors believe that this model is best used create when first starting to use 3D printing technology. Circle of Willis and coronary arterial system 3D printed models, demonstrating complex branch anatomy in various views. The models they created are being used for visualization, handheld spatial reasoning, and for testing in regard to complex segmental and branch anatomy relevant to radiology.įigure 1. The authors describe how they made 3D anatomic models of the liver, lung, prostate, coronary arteries, and the Circle of Willis. The Academic Radiology article also explains how radiologists can create and use low-cost 3D anatomic models. Virtual anatomic data are processed by 3D reconstruction software into a virtual 3D mesh. Low-cost 3D anatomic models are the product of innovations in advanced 3D printing and the capabilities of cross-sectional imaging like high-resolution CT, MRI, and steady-state free precession and fast spoiled gradient-echo.

“A firm understanding of complex anatomy not only serves as the fundamental basis of identifying pathologic states, but also allows for providing accurate reports tailored toward nonradiologist subspecialists and surgeons,” they write. Writing in the September issue of Academic Radiology, lead author Ramin Javan, MD, assistant professor of neuroradiology, and colleagues recommend that radiologists working at academic and/or teaching hospitals utilize 3D anatomic models to enhance the experience of radiology trainees and nonradiologist subspecialists. 3D printing technologies can provide radiologists with an opportunity to serve as leaders in medical education and clinical care, according to radiologists at George Washington University Medical Center in Washington, D.C.
