    Summary
    This summary is machine-generated.

    Computed tomography (CT) is valuable for detecting liver lymphoma, comparable to radionuclide scans. CT is preferred for its ability to also assess abdominal lymph nodes in lymphoma patients.

    Area of Science:

    • Radiology
    • Oncology
    • Medical Imaging

    Background:

    • Lymphoma frequently involves the liver, necessitating accurate detection methods.
    • Computed tomography (CT) and radionuclide scanning are imaging modalities used to assess hepatic involvement in lymphoma.

    Purpose of the Study:

    • To evaluate the diagnostic value of CT in detecting lymphomatous involvement of the liver.
    • To describe the CT appearance of hepatic lymphoma.
    • To compare CT findings with radionuclide scans and histological data.

    Main Methods:

    • Retrospective review of abdominal CT scans in 323 lymphoma patients.
    • Comparison of CT findings with histological studies (95 patients) and radionuclide scans (65 patients).
    • Analysis of sensitivity, specificity, and CT appearance of hepatic lymphoma.

    Main Results:

    • CT demonstrated a sensitivity of 57% and specificity of 88% for hepatic lymphoma.
    • Radionuclide scans showed a sensitivity of 71% and specificity of 81%.
    • No specific CT pattern for hepatic lymphoma was identified, and no correlation with lymphoma type was found.

    Conclusions:

    • CT and radionuclide scans are comparable in detecting hepatic lymphoma.
    • CT is the preferred modality due to its additional capability in evaluating abdominal lymph nodes.
    • Technical artifacts were a common cause of false-positive CT results.
