ABSTRACT
Nuclear Medicine is an imaging modality that uses radioactive tracers to image biological processes. Positron emission tomography (PET) has emerged over the last few decades as a valuable technique in Oncology for prognosis, staging, and therapeutic monitoring in many solid tumors. Most cameras now combine PET with CT (PET-CT), with the CT component used for attenuation correction of images and for anatomic localization. e combination of PET and CT provides volumetric whole body functional and anatomical imaging.1
