Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Radiology

Background:

  • Carotid artery imaging quality is crucial for diagnosing vascular diseases.
  • Current radiofrequency (RF) coil arrays have limitations in optimizing signal-to-noise ratio (SNR).
  • Exploring advanced coil designs can enhance diagnostic accuracy.

Purpose of the Study:

  • To investigate the potential of specialized RF coil arrays to improve carotid artery imaging quality.
  • To determine the optimal configuration of coil arrays for enhanced SNR.
  • To assess the feasibility of using advanced coil arrays in clinical settings.

Main Methods:

  • Computer simulations using analytic near-field equations for magnetic and electric fields of loop resonators.
  • Estimation of relative signal-to-noise ratio (rSNR) based on loop size, position, and vessel depth.

  • Imaging of three human volunteers with various RF coils to measure rSNR along the carotid artery.

    • Main Results:

    • Both simulations and volunteer measurements demonstrated that tailored RF coils significantly improve SNR (>300% at the bifurcation).
    • Region-specific coils outperformed standard four-element arrays designed for whole-carotid coverage.
    • Optimal coil configurations were identified for maximizing SNR across the carotid artery.

    Conclusions:

    • Advanced RF coil arrays, with 16 to 24 ports, can substantially enhance carotid artery imaging.
    • The required number of coil channels aligns with emerging clinical scanner capabilities.
    • This approach promises improved diagnostic capabilities for carotid artery diseases.
