    Area of Science:

    • Cardiology
    • Nuclear Medicine
    • Diagnostic Imaging

    Background:

    • Right ventricular (RV) function is vital in numerous cardiac conditions.
    • Factors like left ventricular function, RV afterload/preload, medications, and ischemia influence RV performance.
    • Quantitative assessment of RV function is essential for patient management.

    Purpose of the Study:

    • To evaluate the role of radionuclide ventriculography in assessing RV function.
    • To explore the potential of newer imaging techniques for improved RV assessment.
    • To highlight limitations and future directions in RV function evaluation.

    Main Methods:

    • Utilized radionuclide ventriculography for quantitative assessment of RV function.
    • Methods included rest, exercise, and pharmacologic interventions.

  • Investigated the first-pass method with short-lived radionuclides.

    • Main Results:

    • Radionuclide ventriculography provides quantitative RV function assessment.
    • Gated scintigraphic techniques face limitations due to right atrium-right ventricle overlap.
    • Newer short-lived radionuclides and the first-pass method show promise for accuracy and reproducibility.

    Conclusions:

    • Accurate assessment of right ventricular function is critical in cardiac care.
    • The first-pass method using advanced radionuclides offers improved RV function evaluation.
    • Further research is needed to refine techniques and understand RV function's prognostic impact.
