Summary

Improving skeletal radionuclide evaluation with single photon emission computed tomography (SPECT) requires quality control and artifact recognition. Simple image processing significantly reduced technical inadequacy rates and enhanced diagnostic quality in hip evaluations.

    • Technical inadequacy rate decreased from 19% to 2% for hip SPECT evaluations.
    • Significant improvement in diagnostic image quality observed.
    • Effective reduction of "hot spot" and bladder pixel overflow artifacts.

    Conclusions:

    • Simple image-processing routines are effective in enhancing SPECT quality for skeletal evaluation.
    • Quality control and artifact management are key to successful SPECT application.
    • These methods improve diagnostic accuracy and reduce technical failures in radionuclide imaging.
