    Area of Science:

    • Nuclear Medicine
    • Radiopharmacology

    Background:

    • Investigating red bone marrow function is crucial for diagnosing and monitoring hematologic and oncologic conditions.
    • Accurate assessment of bone marrow activity requires reliable radiopharmaceuticals and imaging techniques.

    Purpose of the Study:

    • To evaluate the distribution and kinetics of 111In-citrin in the bone marrow.
    • To confirm the functional applicability of 111In-citrin for red bone marrow investigation.
    • To establish methods for radionuclide studies of bone marrow in cancer and leukemic patients.

    Main Methods:

    • Intravenous injection of 111In-citrin in patients without hemopoietic disorders.
    • Measurement of organ fixation and elimination using a total body meter at shortly after injection and 24 hours.

  • Total body scintigraphy at 24 hours post-administration.
  • Correlation analysis between 111In concentration in pelvic bones and RP elimination.

    • Main Results:

    • 111In-citrin showed significant accumulation (up to 20%) in the bone marrow.
    • Pharmacokinetic data confirmed 111In-citrin's suitability for red bone marrow studies.
    • 111In concentration in pelvic bones correlated inversely with RP elimination, reflecting bone marrow activity.
    • Total body scintigraphy visualized bone marrow distribution and identified functional disorders.

    Conclusions:

    • 111In-citrin is a functional radiopharmaceutical for investigating red bone marrow.
    • The study provides data for radiation exposure calculations and methodological improvements in bone marrow radionuclide studies.
    • 111In-citrin scintigraphy aids in detecting bone marrow abnormalities in leukemias and malignancies.
