Three-dimensional (3D) imaging results in highly impressive images that clearly depict internal anatomic structures and can provide diagnostic information beyond what is available in other radiologic imaging modalities. However, the postprocessing image reconstruction needed to create these studies can require considerable staff resources and advanced training. A host of radiologic technologists have taken on the challenge of the additional training needed for 3D image reconstruction and postprocessing, and now serve as resident 3D technologist experts, either within their facility or as staff members of laboratories that specifically provide 3D postprocessing to radiology facilities that are interested in providing 3D imaging services, but are unable to maintain the staff resources to keep up with the demands required for regular postprocessing. 3D imaging has demonstrated value as an important diagnostic tool in a variety of applications in orthopedic and cardiovascular medicine. The growing field of 3D imaging demonstrates the need for advanced 3D training for radiologic technologists, so that these professionals provide consistent quality and are given the support they need in their daily work. This article will describe the current role of 3D technologists, discuss the different challenges presented with onsite or outsourced 3D postprocessing, and present relevant case studies in a variety of medical applications currently aided by 3D postprocessing.
