Brief summary
Prospective, monocentric study aiming to evaluate the PET-CT (Positron Emission Tomography - Computed Tomography) scanner performances to detect infra-centimetric lesions in two groups of patients with cancer and of different BMI (Body Mass Index) classes (BMI ≤ 25 and BMI \> 25). For each patient, two consecutive PET-CT scanner will be performed using the "Discovery MI" and "Discovery IQ" PET-CT scanner systems. Virtual lesions will then be created on images obtained. Images will be interpreted by two independent observers. The study participation of each patient will be a maximum of 24 hours.
Interventions
For each patient, 2 consecutive PET-CT scanners will be performed using 2 different systems of PET-CT scanners: * "Discovery MI" * "Discovery IQ" Only one contrast agent injection (FDG) will be given for both scanners.
