A scar on a CAT scan will not take a glucose and will be negative on a PET skin. PET scan is an imaging technique that uses a radioactive tracer to locate tissue differences at a molecular level. It also looks for spots or nodules elsewhere in the body. 8—Skeletal uptake in 56-year-old woman with known sarcoidosis in neck, who presented with pelvic bone pain. By virtue of the large number of included nodules with different sizes, densities, pathological types, location in the lungs, and detected at the prevalence or incidence rounds, this study sheds light on some of the strengths and limitations of PET to differentiate between malignant and benign indeterminate lung nodules [6, 7, 11].

Since cancer cells are more active than normal cells, the cancer cells take up more of the radiolabeled glucose and show up on the FDG-PET scan. From a societal perspective, one of the known risks of screening is the potentially immense financial cost. If the abnormality does not have characteristics that immediately suggest lung cancer, physicians can do follow-up scans to see if the nodule changes -- for example, grows -- over time.
