Summary
This study releases diffusion-weighted imaging data from individuals with epilepsy, revealing widespread reductions in fractional anisotropy linked to seizure onset areas. This resource aids research into epilepsy
Area of Science:
- Neuroscience
- Radiology
- Medical Imaging
Background:
- Epileptic seizures originate from complex cerebral networks.
- Diffusion-weighted magnetic resonance imaging (DWI) can map these networks.
- Limited public DWI data and processing challenges hinder epilepsy research.
Purpose of the Study:
- To release a comprehensive dataset of raw and processed DWI data from individuals with epilepsy.
- To provide associated clinical and imaging data for advanced research.
- To facilitate studies on structural connectivity and surgical outcomes in epilepsy.
Main Methods:
- Collected raw DWI data from 216 individuals with epilepsy and 98 healthy controls.
- Preprocessed data to reduce artifacts and distortions.
- Generated diffusion metric maps, parcellated structural connectomes, and connectivity measures.
Main Results:
- Replicated ENIGMA consortium findings of reduced fractional anisotropy, especially near seizure onset zones.
- Demonstrated localized abnormalities and network connectivity using streamline tractography.
- Highlighted the utility of the IDEAS II dataset for epilepsy research.
Conclusions:
- The open IDEAS II dataset is a valuable resource for studying structural connectivity in epilepsy.
- This data can advance understanding of network alterations and surgical outcomes.
- Facilitates collaborative research in neuroimaging and epilepsy.
