Computed tomography of the liver.

D H Stephens, P F Sheedy, R R Hattery

    AJR. American Journal of Roentgenology

    Summary

    Computed tomography (CT) of the liver is valuable for diagnosing liver conditions, accurately detecting lesions and fatty infiltration but less effective for diffuse disease. Proper technique and interpretation are crucial for optimal diagnostic value.

    Area of Science:

    • Radiology
    • Medical Imaging
    • Hepatology

    Background:

    • Computed tomography (CT) is a key imaging modality for liver assessment.
    • Understanding the capabilities and limitations of CT is essential for accurate liver diagnosis.
    • Proper examination conduct and interpretation are critical for diagnostic value.

    Purpose of the Study:

    • To evaluate the diagnostic performance of abdominal CT in liver examinations.
    • To document the CT appearance of normal liver variations and hepatic abnormalities.
    • To assess the effectiveness of CT in detecting various liver conditions.

    Main Methods:

    • Retrospective analysis of over 600 abdominal CT liver examinations.
    • Utilized a fast CT system to minimize respiratory motion artifacts.
    • Evaluated the use of contrast material and identified factors affecting technical quality.

    Main Results:

    • CT demonstrated high accuracy in detecting and defining space-occupying lesions and fatty infiltration.
    • CT was less effective in diagnosing diffuse hepatic disease.
    • CT successfully visualized dilated bile ducts and often identified the cause of obstruction.

    Conclusions:

    • Abdominal CT is a highly valuable tool for diagnosing liver space-occupying lesions and fatty infiltration.
    • CT's utility is limited in diffuse hepatic disease, necessitating complementary diagnostic approaches.
    • Optimized CT protocols and expert interpretation enhance diagnostic accuracy for liver pathologies, including bile duct obstruction.
