Hepatic echography.

G Hébert, C Gélinas

    The American Journal of Roentgenology, Radium Therapy, and Nuclear Medicine
    |September 1, 1975
    PubMed
    Summary
    This summary is machine-generated.

    Two key echographic signs help identify liver conditions. The attenuation sign suggests fibrosis or cirrhosis, while posterior echo accumulation indicates fluid-filled cysts in diffuse echogenic patterns.

    Area of Science:

    • Medical Imaging
    • Diagnostic Ultrasound
    • Hepatology

    Background:

    • Echographic investigations are crucial in medical diagnostics.
    • Distinguishing between complementary and specific echographic findings is essential for accurate diagnosis.
    • Improving the specificity of ultrasound examinations can enhance diagnostic capabilities.

    Purpose of the Study:

    • To highlight two specific echographic signs that improve the diagnostic accuracy of ultrasound.
    • To identify echographic indicators for fibrotic and cystic liver conditions.

    Main Methods:

    • Analysis of echographic patterns in diffuse and localized sonolucent findings.
    • Correlation of specific echographic signs with pathological tissue characteristics (fibrotic/liquid).

    Main Results:

    • The attenuation sign in diffuse echogenic patterns is indicative of a fibrotic, likely cirrhotic, liver.
    • The posterior echo accumulation sign in localized sonolucent patterns suggests a liquid, often cystic, nature.

    Conclusions:

    • The attenuation sign is a specific indicator for cirrhotic liver disease.
    • The posterior echo accumulation sign is a reliable indicator for cystic lesions.
    • These signs enhance the diagnostic specificity of ultrasound in liver evaluations.
