In oncology, Positron Emission Tomography imaging with 18Fluor-FDG quantifies glucose metabolism lesions. Conventionally, the metabolism is quantified using the Standard Uptake Value (SUV) from a static acquisition obtained 60 minutes post-injection. Some teams reported SUV variation coefficients as high as 30% in NSCLC lesions for repeated PET examinations in patients without treatment. Moreover, information regarding the binding kinetics of 18Fluor-FDG by tumor cells is not accessible through this method.
