SPECT/CT showed progressive metastatic disease with multiple lesions, which came with only minor uptake in the static scan, but could be detected by means of SPECT/CT
SPECT/CT is clearly superior for the detection of diffuse bone metastases with only minor radiotracer -uptake, that can be missed in planar scans.
" Various studies have llustrated that SPECT SUV may have potential clinical importance, but Its clinical value has not yet been demonstrated. The clinician is ultimately responsible for the final interpretation and diagnosis based on standard practices and visual interpretation of all SPECT data.”
