This study demonstrates parallel imaging for cardiac MRI, enhancing spatial coverage without sacrificing image quality. This technique improves diagnostic capabilities by capturing more heart slices within a single heartbeat.

Area of Science:

  • Cardiovascular Magnetic Resonance Imaging
  • Medical Imaging Physics

Background:

  • First-pass, contrast-enhanced cardiac MRI requires high spatial coverage and temporal resolution for accurate diagnosis.
  • Achieving greater spatial coverage often necessitates compromises in temporal resolution or image quality.

Purpose of the Study:

  • To investigate the efficacy of parallel imaging combined with slice interleaving for enhanced spatial coverage in cardiac MRI.
  • To maintain or improve image quality (SNR and CNR) while increasing spatial coverage.
  • To achieve single-heartbeat temporal resolution across a range of heart rates.

Main Methods:

  • Implementation of a rate R=2 acceleration technique using TSENSE.
  • Utilizing shot-to-shot interleaving of two slices to increase spatial coverage.

  • Optimizing effective repetition time (TR) and flip angle to compensate for SNR loss.

    • Main Results:

    • Achieved increased spatial coverage with comparable or better image quality.
    • Demonstrated single-heartbeat temporal resolution with eight slices at heart rates up to 71 bpm, six slices up to 95 bpm, and four slices up to 143 bpm.
    • Experiments in normal subjects (N=6) assessed signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR).

    Conclusions:

    • Parallel imaging with slice interleaving is an effective strategy for improving spatial coverage in cardiac MRI.
    • This method allows for higher heart rates to be accommodated while maintaining diagnostic image quality.
    • The technique holds promise for enhancing diagnostic accuracy in first-pass, contrast-enhanced cardiac MRI examinations.
