    Digital subtraction angiography (DSA) advances cardiovascular radiology, enabling functional imaging. Parametric imaging techniques offer new ways to detect heart disease by analyzing cardiac contraction and coronary blood flow.

    Area of Science:

    • Cardiovascular Radiology
    • Medical Imaging
    • Digital Angiography

    Background:

    • Digitization is transforming cardiovascular radiology.
    • Digital subtraction angiography (DSA) is increasingly replacing conventional angiography.
    • Intra-arterial injections are favored over intravenous routes for certain procedures due to image quality.

    Purpose of the Study:

    • To explore the advancements in cardiovascular radiology driven by digitization.
    • To highlight the transition towards functional imaging beyond traditional angiography.
    • To introduce parametric imaging techniques for diagnosing cardiovascular conditions.

    Main Methods:

    • Digital subtraction angiography (DSA) for improved imaging.
    • Intra-arterial contrast medium injection with smaller catheters.
