    Imaging Studies I: CT and MRI

    Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
    Description of the Procedures
    Computed Tomography (CT) scan:
    Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

    Federated learning (FL) faces challenges with diverse medical data. FedCMT, a new framework, enables collaborative training across different imaging types and tasks, improving model generalization.

    Area of Science:

    • Artificial Intelligence
    • Medical Imaging
    • Machine Learning

    Background:

    • Federated learning (FL) allows collaborative training on decentralized medical data, preserving privacy.
    • Data heterogeneity in imaging modality (CT, MRI) and tasks (segmentation, classification) limits FL adoption.
    • Existing FL methods struggle to create unified models for diverse medical datasets.

    Purpose of the Study:

    • To propose FedCMT, a modality-agnostic FL framework to address data heterogeneity in medical imaging.
    • To enable flexible adaptation to various input modalities and local tasks within a federated network.
    • To enhance collaboration and generalization in FL for medical image analysis.

    Main Methods:

    • FedCMT incorporates group-wise adapters and personalized decoders for modality- and task-specific feature capture.

  • A conflict-averse module extracts modality-invariant representations, mitigating inter-client feature conflicts.
  • Global-to-local knowledge distillation balances global consistency and local specialization.

    • Main Results:

    • FedCMT demonstrated stability and fostered shared knowledge across diverse medical imaging modalities.
    • Evaluated on ten CT and MR datasets with up to eight clients and varied tasks.
    • Achieved an average improvement of 4.76% over state-of-the-art FL baselines and 4.01% over standalone training.

    Conclusions:

    • FedCMT effectively handles data heterogeneity in medical FL, outperforming existing methods.
    • The framework supports flexible input modalities and diverse local tasks.
    • FedCMT shows promise for real-world medical image analysis applications.
