IMPACT OF ACQUISITION PARAMETERS ON THE QUANTITATIVE ASSESSMENT OF PET IMAGING – ANALYSIS OF THE NEMA PHANTOM
Aim: The aim of the research was to analyse the most common factors that influence SUV values. Material and methods: In the study, I used a NEMA body phantom filled with a mixture of water and 18F-FDG in a ratio 1:4 (background/spheres), and analysed the most common factors that influence SUV values. The most common factors include the impact of the patient's body weight, the impact of time between application and PET/CT imaging, and the impact of differently prepared and administered RP activities. Results: Different values of patient body weight, time between application and PET/CT imaging, and differently prepared and administered RF activities have a statistically significant effect on the quantitative assessment of SUVmax (p < 0.001) and SUVmean (p < 0.001). Conclusion: The results showed that all factors can significantly influence the quantitative assessment of SUVmax and SUVmean.
