Work-up of thyroid incidentalomas identified by 18F-fluorodeoxyglucose PET/CT

Several reports have described dramatic increase over recent decades in the incidence of thyroid cancer, even as thyroid cancer-related mortality rates have not changed substantially. Nevertheless, in several retrospective studies the incidence of malignancy in focal18F-fluorodeoxyglucose (FDG) thyroid uptake discovered on whole body18F-FDG PET/CT, carried out for non-thyroid cancers, is 13-64%. Our aim was to design a practical algorithm for management of an increasing number of thyroid incidentalomas, identified by18F-FDG PET/CT.
