This study introduces a new method for fast 3D whole-heart MRI, improving coronary artery visualization. The Radial Phase Encoding-Phase Ordering with Automatic Window Selection technique enhances image quality and navigator efficiency, even with irregular breathing.

Area of Science:

  • Cardiovascular Imaging
  • Magnetic Resonance Imaging
  • Medical Technology

Background:

  • Three-dimensional (3D) whole-heart magnetic resonance imaging (MRI) is crucial for diagnosing cardiovascular diseases.
  • Challenges include long scan times for high resolution and motion-induced artifacts.
  • Existing methods struggle with physiological motion, especially irregular breathing patterns.

Purpose of the Study:

  • To develop a faster 3D whole-heart MRI technique.
  • To overcome limitations of long acquisition times and motion artifacts.
  • To improve the depiction of coronary arteries and navigator efficiency.

Main Methods:

  • Proposed a novel approach combining interleaved Radial Phase Encoding (RPE) trajectory with Phase Ordering and Automatic Window Selection (PO-AWS).

  • Implemented and simulated the RPE-PO-AWS method.
  • Compared RPE-PO-AWS against a respiratory-gated 3D Cartesian acquisition.

    • Main Results:

    • The RPE-PO-AWS method achieved fast 3D whole-heart imaging with high isotropic resolution.
    • Demonstrated high navigator efficiency, effective even with highly irregular breathing.
    • Showed improved visualization of coronary arteries compared to the Cartesian method.

    Conclusions:

    • The RPE-PO-AWS approach offers a significant advancement for 3D whole-heart MRI.
    • This technique provides high-resolution imaging and dynamic respiratory information without increasing scan time.
    • It effectively addresses key challenges in cardiovascular MRI acquisition.
