Optimization and assessment of quantitative 124I imaging on a Philips Gemini dual GS PET/CT system

Quantitative 124I PET imaging is challenging as 124I has a complex decay scheme. In this study the performance of a Philips Gemini dual GS PET/CT system was optimized and assessed for 124I. The energy window giving the maximum noise equivalent count rate (NECR) and NEMA 2001-NU2 image quality were measured. The activity concentration (AC) accuracy of images calibrated using factors from 18F and 124I decaying source measurements were...
