    Magnetic resonance (MR) imaging is as effective as computed tomography (CT) for detecting hepatocellular carcinoma (HCC). MR imaging offers superior visualization of tumor details, including pseudocapsules, aiding in characterizing HCC's internal architecture.

    Area of Science:

    • Radiology
    • Oncology
    • Medical Imaging

    Background:

    • Hepatocellular carcinoma (HCC) is a primary liver malignancy.
    • Accurate imaging is crucial for HCC diagnosis and characterization.
    • Computed tomography (CT) and magnetic resonance (MR) imaging are key diagnostic modalities.

    Purpose of the Study:

    • To compare the efficacy of CT and 1.5 T MR imaging in detecting and characterizing hepatocellular carcinoma (HCC).
    • To evaluate MR imaging's ability to visualize specific HCC features like pseudocapsules.

    Main Methods:

    • Sixty patients with HCC underwent both CT and 1.5 T MR imaging.
    • Standard spin-echo (SE) sequences (600/25 and 2000/60) were utilized.
    • Image analysis focused on tumor detection and visualization of internal architectural features.

    Main Results:

    • MR imaging demonstrated equivalent detection rates for HCC compared to CT.
    • MR imaging excelled in visualizing tumor pseudocapsules and internal architecture.
    • Specific HCC features like pseudocapsules, septa, daughter nodules, and thrombi were identified with MR imaging.

    Conclusions:

    • MR imaging is a valuable tool for characterizing the internal architecture of hepatocellular carcinoma.
    • MR imaging provides superior detail of tumor components compared to CT.
    • The findings support the utility of MR imaging in managing HCC patients.
