Area of Science:

  • Magnetic Resonance Imaging (MRI)
  • Cardiovascular Imaging
  • Medical Physics

Background:

  • Cardiac function studies require high-resolution, artifact-free imaging.
  • Traditional spin-warp (2D Fourier transform) techniques are sensitive to motion artifacts during cardiac scans.
  • Balanced fast field echo (FFE) sequences, also known as true fast imaging with steady precession (true FISP), offer potential advantages.

Purpose of the Study:

  • To evaluate a balanced projection reconstruction (PR)-FFE sequence for cardiac function studies.
  • To compare the balanced PR-FFE method against conventional spin-warp (2D Fourier transform) techniques.
  • To investigate the representation and mitigation of motion artifacts in cardiac MRI.

Main Methods:

  • Implementation of a balanced PR-FFE sequence with real-time reconstruction and interactive scanning.

    Conclusions:

    • Balanced PR-FFE is a robust and effective tool for cardiac function studies.
    • The technique offers improved motion artifact management and flexible resolution options.
    • Balanced PR-FFE enhances real-time cardiac imaging capabilities.
