    Area of Science:

    • Medical Imaging
    • Biophysics

    Background:

    • Circumferential coils offer broad coverage but have limitations for superficial structures.
    • Surface coils provide a localized approach to magnetic resonance (MR) signal detection.

    Purpose of the Study:

    • To highlight the advantages of surface coils in MR imaging.
    • To discuss the application of different surface coil geometries for various anatomical regions.

    Main Methods:

    • Comparison of signal-to-noise ratio (SNR) between surface and circumferential coils.
    • Description of various surface coil designs (flat, curved, solenoidal, small circumferential).

    Main Results:

    • Surface coils yield a higher signal-to-noise ratio for superficial structures compared to circumferential coils.

  • Improved spatial resolution is achievable with surface coil utilization.
  • Specific coil geometries are suited for particular anatomical targets, such as solenoidal coils for breasts and small circumferential coils for extremities.

    • Conclusions:

    • Surface coils are superior to circumferential coils for imaging superficial structures due to enhanced SNR and spatial resolution.
    • Tailored surface coil geometries optimize MR imaging performance across diverse anatomical regions.
