    Technetium-99m labeled D-pencillamine (Tc-Pen) provides satisfactory gallbladder imaging in dogs and humans. This agent shows potential for evaluating liver (hepatocellular) function.

    Area of Science:

    • Nuclear Medicine
    • Diagnostic Imaging
    • Hepatobiliary System

    Background:

    • Cholescintigraphy is crucial for evaluating gallbladder and biliary tract function.
    • Development of novel radiopharmaceuticals is essential for improving diagnostic accuracy.

    Purpose of the Study:

    • To evaluate the efficacy of 99mTc-labeled D-pencillamine (Tc-Pen) for cholescintigraphy.
    • To assess Tc-Pen's potential as an agent for evaluating hepatocellular function.

    Main Methods:

    • Tc-Pen was administered for cholescintigraphy in canine and human subjects.
    • Imaging was performed using a scintillation camera with a pinhole collimator.
    • Results were compared with contrast cholecystography.

    Main Results:

    Related Experiment Videos

    • Satisfactory gallbladder images were obtained using Tc-Pen.
    • Tc-Pen cholescintigraphy results favorably compared with contrast cholecystography.
    • Tc-Pen appears to be taken up by hepatocytes and excreted into bile.

    Conclusions:

    • Tc-Pen is a viable agent for cholescintigraphy.
    • Tc-Pen demonstrates potential for assessing hepatocellular function.
    • Further investigation into Tc-Pen for liver function evaluation is warranted.
