    This new imaging technique combines serial angiographies to visualize blood flow direction and perfusion. It allows for accurate hemodynamic parameter estimation in a single image, aiding in the assessment of vascular diseases.

    Area of Science:

    • Medical Imaging
    • Cardiovascular Science
    • Radiology

    Context:

    • Assessing blood flow and perfusion is crucial in diagnosing vascular diseases.
    • Traditional angiography methods can be complex and may lose functional details.
    • There is a need for advanced imaging techniques that provide comprehensive hemodynamic information.

    Purpose:

    • To introduce a novel imaging technique that combines phase-differences of serial angiographies.
    • To demonstrate the ability of this technique to visualize functional perfusion without losing morphological details.
    • To evaluate the utility of this method for documenting blood flow direction, hemodynamic parameters, and estimating flow rates.

    Summary:

    • The technique generates combination-images by adding phase-differences of serial angiographies in contrasting colors.
