    Area of Science:

    • Neuroimaging
    • Medical Image Analysis
    • Biomedical Engineering

    Background:

    • Accurate rodent brain extraction is crucial for translational studies using Magnetic Resonance Imaging (MRI).
    • Existing methods for rodent brain extraction have limitations in accuracy and consistency.
    • Modeling brain variation is essential for robust image analysis.

    Purpose of the Study:

    • To develop and evaluate a novel non-rigid B-spline image registration approach for rodent brain extraction in MRI.
    • To model rodent brain shape and appearance variations for improved extraction accuracy.
    • To refine brain extraction using a multi-expert approach.

    Main Methods:

    • Non-rigid B-spline image registration to model rodent brain variations.
    • Modeling of shape and appearance using B-spline parameters and a mean brain image.
    • Multi-expert refinement of the brain extraction region.

    Main Results:

    • The proposed B-spline registration method significantly improved rodent brain extraction performance on one dataset compared to cross-correlation template models.
    • Similar, yet more consistent, performance was achieved on a second dataset.
    • Both template-based methods outperformed the 3D PCNN (voxel-based) and modified BET methods.

    Conclusions:

    • Non-rigid B-spline registration offers a robust and accurate method for rodent brain extraction in MRI.
    • The multi-expert refinement enhances the precision of the extraction process.
    • This approach advances the reliability of rodent brain MRI analysis for translational research.
