Summary

Multiecho echo-planar steady-state free precession (EPI-SSFP) enhances cardiac MRI efficiency and quality. This technique improves scan time and reduces artifacts, offering comparable image quality to single-echo SSFP for cardiac cine imaging.

Area of Science:

  • Magnetic Resonance Imaging
  • Cardiovascular Imaging
  • Medical Physics

Background:

  • Refocused steady-state free precession (SSFP) offers high signal-to-noise ratio (SNR) and excellent blood-myocardium contrast for cardiac imaging.
  • Existing SSFP techniques can be limited by scan time and artifacts, impacting cardiac cine acquisition efficiency.

Purpose of the Study:

  • To present and evaluate various implementations of multiecho SSFP, specifically EPI-SSFP, for cardiac imaging.
  • To assess the efficiency, image quality, and artifact reduction capabilities of EPI-SSFP compared to conventional SSFP.

Main Methods:

  • Implementation of multiecho EPI-SSFP with noninterleaved phase-encode order and phased-array ghost elimination (PAGE) to minimize repetition time (TR).
  • Utilized multishot EPI-SSFP for reduced breath-hold duration or improved resolution in cine acquisitions.

  • Investigated a three-echo acquisition for maximal efficiency gains.

    • Main Results:

    • Multishot EPI-SSFP demonstrated comparable image quality (blood-myocardium contrast, CNR) to single-echo SSFP for cardiac cine applications.
    • The PAGE technique significantly reduced flow artifacts through inherent ghost suppression and reduced blip size.
    • Increased TR in multishot EPI-SSFP led to reduced specific absorption rate (SAR), allowing larger flip angles within FDA limits.

    Conclusions:

    • Multiecho EPI-SSFP provides a significant gain in scan-time efficiency for cardiac imaging.
    • The PAGE technique effectively mitigates flow artifacts, enhancing diagnostic confidence.
    • EPI-SSFP is a valuable advancement for cardiac MRI, improving efficiency and safety profiles.
