Evaluation of the Fractional Uptake Rate (FUR) in 18F-FDG PET/CT to Assess Tumour Metabolic Activity
The goal of this study is to evaluate the use of new method to quantify the amount of sugar a tumor consumes using PET/CT. The main questions it aims to answer are: * Is the new quantification method superior with respect to the method currently used in the clinic? * Does the new quantification method provide accurate assessment of the sugar consumption of tumours? Participants who will undergo a standard care FDG PET/CT scan will in additional receive a dynamic PET/CT scan prior to the standard care scan. In addition blood samples will be drawn at three time points during the examination.
• Patients who receive an 18F FDG PET/CT scan as part of standard care
• Be competent and be 18 years of age or older
