How to Read PET Scan Results: FDG Uptake, SUV and More
Nov 6, 2023 · “Increased FDG uptake” or “Intense FDG uptake” on a PET scan means that cells in a certain area of the body are absorbing more of the radiotracer FDG than surrounding tissues. This higher uptake typically appears as brighter or more intense spots on the scan.

Jul 27, 2016 · Figure 63.1 Transaxial CT (A), PET (B), and PET-CT (C) images of a 76-year-old patient with a known adenocarcinoma of the colon and liver metastases. The patient had no history of thyroid disease, but focal increased FDG uptake was found in the left thyroid lobe.
In 1–2% of PET scans performed for the diagnosis or staging of non-thyroid cancers, incidental uptake of a thyroid lesion is detected. Since 30-40% of these PET-positive lesions are found to be thyroid cancer, current American Thyroid Association guidelines recommends biopsy of all PET-positive nodules >1cm that are not
