Accuracy of Standardized Uptake Values Obtained by Quantitative PET/CT and SPECT/CT

Abstract

Quantification of PET/CT and SPECT/CT using standardized uptake value (SUV) is affected by many factors related to technical factors, such as scanner calibration, imaging physics related factors and patient related factors. Here, I briefly describe some world trend in accuracy of SUVs in PET/CT and SPECT/CT, followed by present and future strategies for clinical practice using SUVs. Finally, I also provided the results of multi-center phantom studies in Japan using SUVs of PET/CT and SPECT/CT.
