Computer-Based Vertebral Tumor Cryoablation Planning and Procedure Simulation Involving Two Cases Using MRI-Visible 3D Printing and Advanced Visualization

AJR Am J Roentgenol. 2016 Nov;207(5):1128-1131. doi: 10.2214/AJR.16.16059. Epub 2016 Aug 9.


Objective: We report the development and use of MRI-compatible and MRI-visible 3D printed models in conjunction with advanced visualization software models to plan and simulate safe access routes to achieve a theoretic zone of cryoablation for percutaneous image-guided treatment of a C7 pedicle osteoid osteoma and an L1 lamina osteoblastoma. Both models altered procedural planning and patient care.

Conclusion: Patient-specific MRI-visible models can be helpful in planning complex percutaneous image-guided cryoablation procedures.

Keywords: 3D printing; additive manufacturing; rapid prototyping; surgical planning; tumor ablation.
