A new cardiac MRI technique, segmented fast gradient-echo with echo-train readout (FGRE-ET), provides high-quality heart images faster. This method reduces blurring and distortion, improving cardiac imaging for stress tests.

Area of Science:

  • Cardiovascular Imaging
  • Magnetic Resonance Imaging (MRI)

Background:

  • Cardiac MRI enables functional assessment but is limited by scan time and artifacts.
  • Conventional techniques like echoplanar imaging (EPI) suffer from geometric distortion and flow artifacts.
  • Faster imaging is crucial for dynamic studies like cardiac stress testing.

Purpose of the Study:

  • To develop and evaluate a novel segmented k-space fast gradient-echo pulse sequence with an echo-train readout (FGRE-ET).
  • To assess the quality of cine cardiac imaging achieved with FGRE-ET in reduced scan times.
  • To compare FGRE-ET against conventional segmented FGRE and EPI for cardiac imaging.

Main Methods:

  • Development of a segmented k-space fast gradient-echo pulse sequence with echo-train readout (FGRE-ET).

  • Acquisition of cine cardiac images using FGRE-ET, segmented FGRE, and multi-phase EPI in normal volunteers.
  • Quantitative and qualitative comparison of image quality, including temporal blurring and geometric distortion.

    • Main Results:

    • Segmented FGRE-ET allows cine imaging of the heart in as few as 1-5 heartbeats.
    • FGRE-ET significantly reduced temporal blurring compared to segmented FGRE (P<0.05).
    • FGRE-ET demonstrated no geometric distortion, unlike conventional EPI (P<0.05).

    Conclusions:

    • Segmented FGRE-ET offers high-quality cardiac cine imaging with reduced scan times.
    • This technique overcomes limitations of EPI, such as geometric distortion and flow artifacts.
    • FGRE-ET is well-suited for functional cardiac stress testing due to its speed and versatility in short breath-holds.
