“…In adults, thoracoscopic lobectomy with use of a fissureless technique requires display of the lung beyond current 3D visualization because of the complexity of the airways (61). Three-dimensional printed models augmented the planning of thoracoscopic segmentectomy in a patient with lung cancer, as well as the planning of another thoracoscopic lung surgery in a patient with rare anatomic variations (62). For mediastinal tumor resection, a 3D model provided unique data on the relationship between a thymoma and adjacent structures (62).…”

While use of advanced visualization in radiology is instrumental in diagnosis and communication with referring clinicians, there is an unmet need to render Digital Imaging and Communications in Medicine (DICOM) images as three-dimensional (3D) printed models capable of providing both tactile feedback and tangible depth information about anatomic and pathologic states. Three-dimensional printed models, already entrenched in the nonmedical sciences, are rapidly being embraced in medicine as well as in the lay community. Incorporating 3D printing from images generated and interpreted by radiologists presents particular challenges, including training, materials and equipment, and guidelines. The overall costs of a 3D printing laboratory must be balanced by the clinical benefits. It is expected that the number of 3D-printed models generated from DICOM images for planning interventions and fabricating implants will grow exponentially. Radiologists should at a minimum be familiar with 3D printing as it relates to their field, including types of 3D printing technologies and materials used to create 3D-printed anatomic models, published applications of models to date, and clinical benefits in radiology. Online supplemental material is available for this article.

“…In that study, of 19 surgeons who used a total of 52 models of tumors throughout the body, 94% considered them very helpful for treatment planning, and 71% felt they improved the surgical approach. To our knowledge, 3D‐printed models specific to thoracic tumors have been reported for two patients with Pancoast tumors, a pediatric patient with primary mediastinal synovial sarcoma invading the SVC, a patient with an ectopic mediastinal thymoma, a patient with a pectoralis minor muscle spindle cell neoplasm, and a patient with a cardiac schwannoma . Benefits reported for these cases include better understanding of tumor relationship to surrounding normal tissues, helping to avoid resecting uninvolved structures, and enhancing the likelihood of complete resection.…”

Background and Objectives 3D-printed models are increasingly used for surgical planning. We assessed the utility, accuracy and reproducibility of 3D printing to assist visualization of complex thoracic tumors for surgical planning. Methods Models were created from pre-operative images for three patients using a standard radiology 3D workstation. Operating surgeons assessed model utility using the Gillespie scale (1=inferior to 4=superior), and accuracy compared to intraoperative findings. Model variability was assessed for one patient for whom two models were created independently. The models were compared subjectively by surgeons and quantitatively based on overlap of depicted tissues, and differences in tumor volume and proximity to tissues. Results Models were superior to imaging and 3D visualization for surgical planning (mean score=3.4), particularly for determining surgical approach (score=4) and resectability (score=3.7). Model accuracy was good to excellent. In the two models created for one patient, tissue volumes overlapped by >86.5%, and tumor volume and area of tissues ≤1mm to the tumor differed by <15% and <1.8cm2, respectively. Surgeons considered these differences to have negligible effect on surgical planning. Conclusion 3D printing assists surgical planning for complex thoracic tumors. Models can be created by radiologists using routine practice tools with sufficient accuracy and clinically negligible variability.
