    Single-photon emission computed tomography (SPECT) significantly enhances the detection of small, photon-deficient lesions compared to conventional nuclear medicine imaging. SPECT offers superior lesion-to-background contrast, crucial for early disease identification.

    Area of Science:

    • Nuclear Medicine
    • Medical Imaging
    • Radiology

    Background:

    • Evaluating imaging techniques for detecting small, photon-deficient lesions in uniform backgrounds.
    • Utilizing Tc-99m sulfur colloid liver phantom models for experimental analysis.

    Purpose of the Study:

    • To compare the effectiveness of conventional nuclear medicine imaging and SPECT in detecting small photon-deficient areas.
    • To quantify the differences in lesion-to-background contrast between the two imaging modalities.

    Main Methods:

    • Analytical and experimental evaluation of conventional and SPECT imaging.
    • Using a liver phantom with 1 and 1.5 cm photon-deficient areas within an Alderson body phantom.
    • Assessing lesion image contrast considering spatial resolution, Compton scatter, and radionuclide superposition.

    Main Results:

    • SPECT imaging demonstrated a significant increase in lesion-to-background contrast compared to conventional imaging.
    • SPECT contrast was essentially independent of radionuclide superposition and attenuation effects.
    • Measured SPECT contrasts for small lesions averaged over five times higher than conventional imaging contrasts.

    Conclusions:

    • SPECT imaging is substantially more effective than conventional nuclear medicine for detecting small, photon-deficient lesions.
    • SPECT's improved contrast is attributed to its reduced sensitivity to superposition and attenuation artifacts.
    • These findings highlight SPECT's advantage in improving diagnostic accuracy for subtle lesions.
