Clinical value of PET-CT whole body imaging in detecting incidental increased ¹⁸F-flurodeoxygiucase uptake in thyroid gland

¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) PET-CT is a noninvasive whole-body imaging technique used to evaluate various types of malignancies. Recent advances have rapidly developed it into a diagnostic imaging modality in oncology. Focal or diffusely increased ¹⁸F-FDG uptake in the thyroid grand with non-thyroid patients in PET-CT scanning, which may be related with thyroid cancer or chronic lymphocytic thyroiditis.
