Summary
The RSNA-ACR 3D Printing Registry shows that 3D printing is widely used in healthcare for patient-specific anatomic models and guides, demonstrating significant clinical benefits and time savings.
Area of Science:
- Medical Imaging and Informatics
- Biomedical Engineering
- Health Services Research
Background:
- Three-dimensional (3D) printing is increasingly adopted in healthcare for creating patient-specific anatomic models and surgical guides.
- The Radiological Society of North America (RSNA) and the American College of Radiology (ACR) established a registry to track the use and impact of 3D printing in clinical settings.
Purpose of the Study:
- To analyze data from the first three years of the RSNA-ACR 3D Printing Registry.
- To understand the demographics, clinical indications, workflows, and user-reported outcomes associated with 3D printing in healthcare.
Main Methods:
- Data collection spanned June 2020 to June 2023, encompassing 20 sites and 2,637 cases.
- Analysis included patient demographics, organ system indications, imaging modalities, printing technologies, staff effort, and user satisfaction via Likert scale questionnaires.
- Workflow data were categorized by provider and nonprovider staff roles.
Main Results:
- The registry included 1,863 anatomic models and 774 anatomic guides, with cardiac and neurologic applications being most common, respectively.
- Material jetting, vat photopolymerization, and material extrusion were the predominant printing technologies.
- Clinical users reported increased confidence in treatment plans (P < .001) and an average procedure time saving of 40.5 minutes.
Conclusions:
- Three-dimensional printing is a valuable tool in healthcare, utilized across diverse clinical indications.
- The registry provides crucial insights into the technologies, workflows, and demonstrated clinical advantages of 3D printing for anatomic models and guides.
