Comparative evaluation of 99mTc-generators.

N Vinberg, K Kristensen

    European Journal of Nuclear Medicine
    |December 30, 1976
    PubMed
    Summary

    This study evaluated 34 technetium-99m (99mTc) generators from eight manufacturers. Most generators performed reliably, meeting quality standards, though some experienced mechanical issues or low elution yields.

    Area of Science:

    • Nuclear Medicine
    • Radiopharmacy

    Background:

    • Technetium-99m (99mTc) is a crucial radionuclide for diagnostic imaging.
    • Reliable 99mTc generators are essential for nuclear medicine procedures.

    Purpose of the Study:

    • To assess the performance and eluate quality of 99mTc generators.
    • To identify potential issues affecting generator reliability and 99mTc quality.

    Main Methods:

    • Evaluation of 34 99mTc generators from eight manufacturers.
    • Assessment of generator performance, elution yield, and eluate quality.
    • Comparison against Nordic Pharmacopeia standards.

    Main Results:

    • Generators generally performed well, serving as reliable 99mTc sources.
    • Minor issues included mechanical malfunctions (2 cases) and low elution yields (2 cases).
    • Four generators were overloaded with molybdenum-99 (99Mo).
    • Most 99mTc eluates met Nordic Pharmacopeia requirements.

    Conclusions:

    • 99mTc generators from various manufacturers demonstrated good performance and reliability.
    • Quality control is essential to address occasional mechanical issues and ensure optimal elution yields.
    • The study confirmed the suitability of these generators for clinical applications.
