目的提出一种经过证实的肺癌病人18F-FDGPET成像肿瘤SUV时间校正方法。材料与方法二室模型分析表明,当未对18F进行物理衰变校正(SUVuncorr)时,针对每例病人,注射55~110min后,SUV衰变值介于峰值(t=79min)的5%以
OBJECTIVE: To propose a method to correct the SUV time of 18F-FDG PET tumor in confirmed lung cancer patients. Materials and Methods Two-compartment model analysis showed that the SUV decay value for each patient ranged from 5% at peak (t = 79 min) for each patient after 55-110 min of injection when 18F was not physically decay corrected (SUVuncorr)
