$\texttt{DisMorph}$: learning to disentangle technical distortions from true biological change
TL;DR
DisMorph is a novel MRI registration framework that separates technical distortions from true biological changes in brain scans. It improves the accuracy of detecting anatomical changes in neurodegenerative diseases like Alzheimer's by addressing distortions caused by MRI acquisition systems.
✦ Why It Matters
Implement DisMorph in your MRI analysis pipeline to improve the accuracy of brain change detection.
Key Takeaways
- Utilize DisMorph for improved MRI registration accuracy.
- Train models on synthetic data to enhance generalization.
- Separate technical distortions from biological changes in imaging.
- Apply findings to clinical settings for better patient assessments.
How It Works
DisMorph employs a generative model to create synthetic MRI data that simulates both technical distortions and anatomical changes. This allows the framework to learn to predict two distinct deformation fields: one for the technical distortions, such as GNL, and another for the true biological changes.
By training on this synthetic data, DisMorph can effectively disentangle the two effects during actual MRI analysis.
