    Radionuclide venography is a reliable diagnostic tool for detecting deep-vein thrombosis. This imaging technique showed high concordance with contrast venography in identifying venous thrombosis.

    Area of Science:

    • Vascular imaging
    • Nuclear medicine
    • Diagnostic radiology

    Background:

    • Deep-vein thrombosis (DVT) diagnosis relies on imaging techniques.
    • Assessing the accuracy of radionuclide venography (RNV) against contrast venography (CV) is crucial.

    Purpose of the Study:

    • To compare the diagnostic accuracy of RNV and CV in detecting DVT.
    • To evaluate the reliability of RNV in identifying thrombosis characteristics.

    Main Methods:

    • 47 limbs across 35 patients underwent both RNV and CV.
    • Findings from both imaging modalities were compared for location and characteristics.
    • Positive RNV findings included decreased radioactivity flow, abnormal collateral flows, and radioactivity stasis.

    Main Results:

    Related Experiment Videos

    • Overall concordance between RNV and CV was 89%.
    • Delayed radioactivity clearance in the calf alone was not indicative of DVT.
    • RNV effectively identified thrombosis location and characteristics.

    Conclusions:

    • Radionuclide venography is a technically simple and reliable method for diagnosing DVT.
    • RNV demonstrates high accuracy comparable to contrast venography.
    • This supports RNV as a valuable tool for patients with suspected DVT.
