Area of Science:

  • Medical Imaging
  • Magnetic Resonance Imaging (MRI)
  • Radiology

Background:

  • Extended field of view (FOV) MRI is crucial for comprehensive anatomical coverage.
  • Acquiring high-resolution 3D MRI over large FOVs presents challenges in scan time and motion artifacts.
  • Continuous patient table motion offers a potential solution for extended FOV imaging.

Purpose of the Study:

  • To develop and validate a 3D MRI method enabling extended FOV imaging.
  • To address challenges associated with patient motion during extended FOV acquisitions.
  • To demonstrate the feasibility of high-quality extended FOV imaging using continuous table motion.

Main Methods:

  • Utilized a gradient-echo MR pulse sequence with lateral frequency encoding and motion-directional slab selection.

  • Implemented slab tracking and hybrid space data alignment for table motion compensation.
  • Integrated segmented k-space scanning for contrast variation and magnetization preparation.

    • Main Results:

    • Achieved fast k-space coverage, particularly with shorter sampling FOVs along the motion direction.
    • Acquired high-quality, head-to-toe 3D MRI images of volunteers.
    • Demonstrated successful fat/water separated imaging using chemical shift selective (CHESS) presaturation pulses.

    Conclusions:

    • The presented method effectively enables 3D MRI in an extended FOV using continuous patient table motion.
    • The technique allows for efficient k-space coverage and high-quality image acquisition.
    • The method is versatile and can be incorporated into various imaging schemes, including magnetization-prepared sequences.
