Abstract

Quantitation in Emission Tomography (PET and SPECT) requires that several physical factors are taken into account. Attenuation, which can be determined on SPECT and PET devices, can be corrected using transmission tomography. Here, the authors quantitatively compared the relative performance of transmission scans in SPECT and PET using a calibrated liquid solution with a linear attenuation coefficient (μ) nearly equivalent to that of skeletal cranium bone over the range of energies 50 to 600 keV. The authors showed that contrast recovery are similar in PET and SPECT for large structures (>30 mm), but higher in PET as object size decreases
