    This study introduces a phase contrast magnetic resonance imaging (MRI) method for visualizing vascular anatomy and blood flow. The technique accurately measures flow volume and produces angiographic views of arteries and veins.

    Area of Science:

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

    Background:

    • Magnetic resonance imaging (MRI) is crucial for non-invasive anatomical visualization.
    • Quantifying blood flow dynamics non-invasively remains a challenge in medical imaging.

    Purpose of the Study:

    • To develop and validate a phase contrast MRI technique for projective imaging of vascular anatomy and flow.
    • To demonstrate the proportionality between image intensity and proton flow volume.

    Main Methods:

    • Utilized phase contrast at 0.14 Tesla to suppress stationary background signals.
    • Employed a conventional 2D Fourier transform (2D FT) spin-echo pulse sequence with short echo times.
    • Phase shifts less than 45 degrees were used to achieve a simple and useful phase contrast form.

    Main Results:

    • Flow image intensity was found to be directly proportional to the net flux or flow volume of protons crossing each voxel.
    • Demonstrated reproducibility of measured flow volume across various imaging conditions and subjects using flow phantoms.
    • Successfully generated in vivo angiographic views of arteries and veins in both systole and diastole.

    Conclusions:

    • The developed phase contrast MRI method provides accurate projective imaging of vascular structures and blood flow.
    • The technique enables non-invasive angiographic visualization of both arteries and veins.
    • This method shows promise for quantitative flow assessment and detailed vascular imaging.
