Area of Science:

Neuroimaging data analysis
Statistical inference in neuroimaging
Machine learning applications in medical imaging

Background:

Voxel-based multiple testing is standard in neuroimaging but traditional methods lack power due to ignored spatial dependence.
Existing spatial false discovery rate (FDR) methods struggle with complex brain spatial dependencies.
Deep learning excels at image segmentation, a related task, offering potential for improved neuroimaging analysis.

Purpose of the Study:

To introduce DeepFDR, a novel spatial FDR control method for voxel-based neuroimaging analysis.
To leverage unsupervised deep learning-based image segmentation for enhanced FDR control.
To improve statistical power and computational efficiency in neuroimaging studies.

Main Methods:

Developed DeepFDR, integrating unsupervised deep learning for image segmentation into spatial FDR control.
Conducted comprehensive simulations to evaluate DeepFDR's performance.
Applied DeepFDR to Alzheimer's disease FDG-PET image analysis.

Main Results:

DeepFDR demonstrated superior performance compared to existing methods in both simulations and real-world neuroimaging data.
The method achieved effective FDR control and significantly reduced the false nondiscovery rate.
DeepFDR exhibited high computational efficiency, suitable for large-scale neuroimaging datasets.

Conclusions:

DeepFDR offers a powerful and efficient solution for voxel-based multiple testing in neuroimaging.
The integration of deep learning improves spatial FDR control, addressing limitations of traditional and existing spatial methods.
DeepFDR is a promising tool for advancing neuroimaging research, particularly in disease analysis like Alzheimer's.
