    Summary

    This study highlights 123I-rose bengal (123I-RB) as a superior diagnostic agent for liver and biliary tract diseases. Its low radiation exposure allows for combined functional and structural imaging, especially beneficial for patients with high bilirubin levels.

    Area of Science:

    • Nuclear Medicine
    • Diagnostic Imaging
    • Hepatobiliary System Studies

    Background:

    • Current diagnostic methods for liver and biliary tract diseases have limitations.
    • Radiopharmaceuticals (RPs) are crucial for assessing hepatobiliary function and structure.
    • There is a need for agents with improved safety profiles and diagnostic capabilities.

    Purpose of the Study:

    • To evaluate the diagnostic efficacy of iodine-123 labeled rose bengal (123I-RB).
    • To compare 123I-RB with standard radiodiagnostic agents.
    • To assess the utility of 123I-RB in patients with elevated bilirubin levels.

    Main Methods:

    • Synthesis of 123I-RB at the B. P. Konstantinov Leningrad Institute of Nuclear Physics.
    • Diagnostic investigations involving 201 patients with liver and biliary tract diseases.
    • Analysis of functional and scintigraphic data obtained using 123I-RB.

    Main Results:

    • 123I-RB demonstrated advantages over standard RPs for liver and biliary tract diagnostics.
    • Lower radiation exposure enabled the use of higher 123I-RB activity (≥120 MBq).
    • Combined functional and structural imaging of the hepatobiliary system was achieved.

    Conclusions:

    • 123I-RB is an effective radiodiagnostic agent for evaluating liver and biliary tract diseases.
    • Its safety profile allows for enhanced diagnostic procedures, including combined functional and structural assessment.
    • 123I-RB is particularly valuable for imaging liver function and topography in hyperbilirubinemic patients.
