    Area of Science:

    • Cardiology
    • Nuclear Medicine
    • Medical Imaging

    Background:

    • Minimal cardiac transit times reflect maximal cardiac blood flow velocity.
    • These times correlate with mean velocity and ejection fraction, key indicators of heart function.

    Purpose of the Study:

    • To evaluate the sensitivity, reproducibility, and clinical utility of minimal cardiac transit times.
    • To demonstrate the method's capability in detecting subtle cardiac function alterations.

    Main Methods:

    • Utilized short-lived radionuclides and a fast gamma camera for measurement.
    • Conducted over 4,000 measurements across diverse patient groups.

    Main Results:

    • Proven sensitivity, reproducibility, and clinical usefulness in over 4,000 patient measurements.
    • Successfully applied in ischemic heart disease, myocardial insufficiency, valvular disease, and hypothyroidism.

    Conclusions:

    • Minimal cardiac transit time measurement is a highly sensitive, reproducible, and clinically valuable tool.
    • The method effectively detects minor cardiac function changes not easily identified by other means.
