Gastric visualization and image quality in radionuclide bone scanning: concise communication.

M A Wilson, M J Pollack

    Journal of Nuclear Medicine : Official Publication, Society of Nuclear Medicine
    |June 1, 1981
    PubMed
    Summary

    Gastric visualization during bone imaging is a rare event linked to radiopharmaceutical quality. This phenomenon stems from agent oxidation during incubation, affecting scan quality and causing gastric activity.

    Area of Science:

    • Nuclear Medicine
    • Radiopharmacy
    • Medical Imaging

    Background:

    • Gastric visualization is an uncommon finding in bone scintigraphy.
    • This effect has been observed sporadically during routine bone imaging procedures.

    Purpose of the Study:

    • To investigate the cause of gastric visualization during bone imaging.
    • To identify factors correlating with the occurrence and severity of gastric visualization.

    Main Methods:

    • Retrospective analysis of bone imaging studies over a 12-month period.
    • Comparison of patient groups with and without gastric visualization.
    • Correlation analysis between gastric visualization and radiopharmaceutical parameters.

    Main Results:

    Related Experiment Videos

    • Gastric visualization occurred on 14 days during the study period, affecting 44% of patients on those days.
    • Significant differences were noted in quality control, binding efficiency, and scan quality compared to a reference population.
    • A strong linear correlation (p < 0.001) was found between gastric visualization and radiopharmaceutical incubation/quality control.

    Conclusions:

    • Gastric visualization during bone imaging is a sporadic phenomenon.
    • Partial oxidation of the radiopharmaceutical during incubation is the likely cause.
    • Oxidation leads to altered diphosphonate species affecting bone uptake and free pertechnetate causing gastric activity.
