    Area of Science:

    • Neuroimaging
    • Artificial Intelligence in Medicine
    • Spinal Cord Imaging

    Background:

    • Structural Magnetic Resonance Imaging (sMRI) is crucial for diagnosing Amyotrophic Lateral Sclerosis (ALS).
    • Spinal cord sMRI analysis is limited by its small axial dimensions and extensive sagittal/coronal views, often restricting diagnosis to morphological observation.
    • Accurate and sensitive identification of ALS through spinal cord sMRI remains a significant clinical challenge.

    Purpose of the Study:

    • To develop an advanced deep learning method for improved Amyotrophic Lateral Sclerosis (ALS) identification using spinal cord sMRI.
    • To overcome the limitations of traditional sMRI analysis in spinal cord imaging for ALS diagnosis.
    • To enhance the extraction of relevant features from spinal cord sMRI for more precise ALS detection.

    Main Methods:

    • A Multi-branch attention-based deep learning framework was designed for spinal cord sMRI analysis.
    • The multi-branch architecture extracts general features across all spinal cord levels, addressing challenges posed by long sagittal and coronal expansions.
    • Attention and multi-scale modules within each branch capture multi-scale features and focus on critical spinal cord regions in the axial plane.

    Main Results:

    • The proposed deep learning method demonstrated superior performance in identifying Amyotrophic Lateral Sclerosis (ALS).
    • Experimental results indicate the model's capability to effectively extract features from diagnostically important spinal cord regions.
    • The approach shows potential for identifying novel regions sensitive to ALS disease progression.

    Conclusions:

    • The developed Multi-branch attention-based deep learning method significantly improves ALS identification from spinal cord sMRI.
    • This technique offers a promising advancement beyond simple morphological observation in spinal cord imaging for ALS.
    • The findings suggest this method can aid in discovering new imaging biomarkers for ALS detection and management.
