PET CT Scan (Whole Body)
What is PET CT Scan (Whole Body)?
Positron emission tomography (PET) uses small amounts of radioactive materials called radiotracers, a special camera and a computer to help evaluate your organ and tissue functions. By identifying body changes at the cellular level, PET may detect the early onset of disease before it is evident on other imaging tests. A PET scan measures important body functions, such as blood flow, oxygen use, and sugar (glucose) metabolism, to help doctors evaluate how well organs and tissues are functioning. It's used to detect cancer, the spread of cancer, to assess the effectiveness of treatment plan.
