Abstract
To establish a feasible and practical methodology for harmonization of FDG-PET, we have investigated quantitative physical performance of recent clinical PET scanners (23 scanners) using the NEMA image quality phantom. Compared with the previous phantom data (13 scanners) acquired in the early 2000s, the current phantom data showed better contrasts of small spheres even with a smaller number of coincidence counts. This result suggests that clinical PET image quality and small lesion detectability might have been significantly improved in the past 10 years. Based on the data acquired in this working group, we are planning to update the standard phantom test methodology and harmonizing criteria for FDG-PET.
