Importance of gated CT acquisition for the quantitative improvement of the gated PET/CT in moving phantom

Objective The aim of this study was to investigate the utility of gated PET/CT and CT attenuation correction (AC) for the quantitation of radioactivity. Methods An ellipse phantom containing six spheres, ranging from 10 to 37 mm in diameter, was filled with 36.7 kBq/mL of F-18. The respiratory motio...
