Q: 54 year old female with no past medical history is admitted to ICU due to shortness of breath requiring intubation. Over the course of the days patient is diagnosed with Non Small Cell Lung Cancer (NSCLC). Radiation-oncologist calls you saying: "Patient has high standardized uptake value (SUV)". What does it means?


During staging of Lung cancer Positron emission tomography (PET) measures tumor's metabolic activity and get reported as standardized uptake value (SUV) to assess the tumor uptake of fluorodeoxyglucose (FDG). A  high SUV is associated with a poor prognosis and a lower FDG uptake is associated with a better prognosis.
