MedUni Vienna and TU Wien collaborated to develop a 3D printed brain phantom, mimicking nerve structures. Published in “Advanced Materials Technologies,” the research aids research into neurodegenerative diseases like Alzheimer’s and Parkinson’s. By refining diffusion-weighted MRI (dMRI) analysis, it enhances brain imaging and diagnostic precision.
MRI is invaluable in brain examination, offering ionizing radiation-free insights. However, dMRI struggles at nerve fiber crossing points. Enter the brain phantom—a tiny, cube-shaped structure filled with microchannels, resembling cranial nerves, printed using two-photon polymerization. This sophisticated technique enables high-resolution printing, crucial for simulating intricate nerve networks.
Collaborating with Zurich and Hamburg-Eppendorf universities, TU Wien’s expertise in 3D printing and MedUni Vienna’s MRI proficiency converged to refine this technique. The phantom, though visually dissimilar to a real brain, serves as a vital tool for training dMRI analysis software. It accurately replicates complex nerve structures, enabling precise software calibration.
Despite successes, challenges persist, notably in scaling up production speed. While two-photon polymerization achieves micro- and nanoscale detail, printing larger objects is time-consuming. Overcoming this hurdle is crucial for broader application.
MedUni Vienna and TU Wien’s collaboration introduces a new era in neuroimaging. The 3D printed brain phantom promises enhanced dMRI analysis, facilitating improved diagnostics and advancing research into debilitating neurological conditions.
