Three-Dimensional Printing for Procedure Rehearsal/Simulation/Planning in Interventional Radiology

Area of Science:

• Medical Imaging and Technology
• Biomedical Engineering
• Radiology

Background:

• Affordable three-dimensional (3D) printing technology is increasingly vital in medicine.
• Patient-specific 3D models enhance medical education and procedural planning.
• 3D models improve physician spatial perception and tactile feedback for team-based operational planning.

Purpose of the Study:

• To provide physicians with an update on current 3D reconstruction software, printers, and materials.
• To explore the application of 3D printing in interventional radiology.
• To share initial experiences with 3D printing for patient-specific anatomical models.

Main Methods:

• Review of current 3D reconstruction software features for anatomical segmentation.
• Evaluation of various 3D printing technologies and materials.
• Case study: Development of a 3D printed aorta for a patient with abdominal aortic stenosis.

Main Results:

• Effective 3D reconstruction necessitates expertise in software for accurate anatomical segmentation from medical imaging (CT, 3D angiography, MRI).
• A range of 3D printers and materials are available, requiring careful selection based on application.
• Initial case demonstrated successful creation of a patient-specific 3D printed aorta.

Conclusions:

• Understanding 3D reconstruction technology and its applications is crucial for radiologists.
• 3D printing offers significant potential for improving interventional radiology techniques and patient care.
• Further development and adoption of 3D printing in clinical practice are anticipated.
