Magnetic resonance imaging (MRI) offers a non-invasive alternative to coronary angiography (CA) for assessing coronary arteries. Advances in MRI techniques, including parallel imaging and contrast agents, promise to enhance its diagnostic capabilities for reliable magnetic resonance coronary angiography (MRCA).

Area of Science:

  • Cardiovascular Imaging
  • Medical Physics

Background:

  • Coronary angiography (CA) is the current gold standard for coronary artery assessment but involves ionizing radiation and invasiveness.
  • Patient-friendly imaging modalities are sought to overcome CA limitations.
  • Magnetic resonance imaging (MRI) is a promising non-invasive alternative.

Purpose of the Study:

  • To explore the potential of MRI as a comprehensive tool for cardiac and coronary artery evaluation.
  • To highlight advancements in MRI techniques for improved coronary angiography.

Main Methods:

  • Assessment of various MRI techniques, including breath-hold and free-breathing 2D and 3D measurements.
  • Exploration of parallel MRI acquisition techniques like simultaneous acquisition of spatial harmonics (SMASH) and sensitivity encoding (SENSE).

  • Investigation of intravascular contrast agents for enhanced imaging.

    • Main Results:

    • MRI offers high anatomical definition and excellent soft tissue contrast.
    • MRI allows for comprehensive cardiac and coronary evaluation in a single session.
    • Parallel imaging techniques (SMASH, SENSE) show potential for reducing scan times.

    Conclusions:

    • MRI is a flexible and non-invasive modality with significant potential for cardiovascular assessment.
    • Further development with contrast agents and advanced acquisition techniques is crucial for reliable magnetic resonance coronary angiography (MRCA).
    • MRI is poised to become a major cardiovascular imaging modality in the future.
