The Radiological Society of North America (RSNA) published in the November 2018 issue of 3D Printing in Medicine consensus guidelines on the clinical use of medical 3D printing. The recommendations, issued by the RSNA’s Special Interest Group on 3D Printing, provide guidance for approaches and tools in medical 3D printing relating to image acquisition, anatomical segmentation, creation of 3D-printable models, and post-processing of 3D-printed anatomic patient care models.
The American College of Radiology’s ACR Appropriateness Criteria were followed to rate appropriateness for clinical use. Scoring ranks from 1 to 9, with 9 representing the strongest recommendations by the special interest group. Scores have been created for three breast conditions, 28 congenital heart disease conditions, 28 craniomaxillofacial conditions, 17 genitourinary conditions, 17 musculoskeletal conditions, and 25 vascular conditions.
“3D printed models represent an advanced form of communication of the data in medical images and may include the summation of data from multiple sources,” wrote lead author Leonid Chepelev, MD, a radiologist at the Ottawa Hospital Research Institute of the University of Ottawa in Ontario. “These practice parameters and recommendations are not intended as comprehensive standards but do reflect several salient aspects of clinical anatomic modeling and appropriateness.”
This consensus document represents the first step for methodology and standardization of clinical applications for 3D printing. The document is expected to be expanded and refined as clinical applications and techniques evolve.
