Creating pathology models from MRI data: a comparison of virtual 3D modelling and rapid prototyping techniques

Area of Science:

• Anatomical modeling
• Medical education
• Renal cancer research

Background:

• Traditional anatomical education relies on cadavers and two-dimensional images.
• The use of three-dimensional (3D) models offers enhanced visualization of complex structures.
• Digital and physical models are emerging tools in medical training.

Purpose of the Study:

• To evaluate the effectiveness of virtual 3D and physical rapid prototype models for teaching renal anatomy in the context of cancer.
• To compare user preference between virtual and physical anatomical models.

Main Methods:

• A pilot study was conducted using anonymized patient MRI data of renal cancer.
• Virtual 3D and two physical rapid prototype models of the kidneys and surrounding anatomy were created.
• A questionnaire assessed feedback from tutors and students on model usability and preference.

Main Results:

• The study generated both virtual 3D and physical rapid prototype models from patient MRI data.
• Feedback indicated a strong user preference for the physical models over the virtual 3D model.
• Both model types were evaluated for their educational utility by tutors and students.

Conclusions:

• Physical rapid prototype models may offer superior educational benefits compared to virtual 3D models for renal anatomy and cancer visualization.
• Further research into the integration of 3D printing in medical curricula is warranted.
• Enhanced anatomical visualization aids in understanding complex pathologies like renal cancer.
