    Area of Science:

    • Medical Imaging
    • Biophysics
    • Radiology

    Background:

    • Current magnetic resonance (MR) imaging techniques for breast evaluation can be limited by sensitivity and resolution.
    • Simultaneous imaging of both breasts is desirable for direct comparison and improved patient throughput.

    Purpose of the Study:

    • To design and evaluate a dedicated MR coil for simultaneous bilateral breast imaging.
    • To assess the performance characteristics of the new coil in terms of sensitivity, resolution, and artifact reduction.

    Main Methods:

    • Development of a triple-coil structure (two outer, one central) for simultaneous bilateral breast imaging.
    • Integration of separate transmitter and receiver coils within a prone positioning system.
    • Compatibility testing with a 0.15-T resistive-magnet MR unit.

    Main Results:

    • The breast coil demonstrated 3-7 times greater image-reception sensitivity compared to a whole-body coil.
    • Achieved thinner imaging sections (5 mm) with improved spatial variation and reduced motion artifacts.
    • Eliminated sensitivity to surrounding organs like the heart and lungs, enhancing image quality and resolution.

    Conclusions:

    • The designed MR coil significantly enhances sensitivity and image quality for bilateral breast imaging.
    • Simultaneous imaging capability improves diagnostic comparison and increases patient throughput in breast MRI.
    • This coil represents a valuable advancement for breast MR imaging protocols.
