Abstract

18 F-FDG-avid thyroid incidentaloma (TI) is seen in approximately 2.5% of patients imaged for staging or response assessment of malignancy and represents thyroid cancer in approximately 35% of cases. Consequently, the 2015 American Thyroid Association guidelines strongly recommend investigation of all 18 F-FDG-avid nodules 1 cm or larger with ultrasound and fine-needle aspiration cytology (FNA). This study aimed to assess the overall and thyroid cancer-specific survival in a large cohort of patients with 18 F-FDG-avid TI with long-term follow-up to assess the validity of this approach. Methods: Retrospective review of 45,680 PET/CT scans performed at a comprehensive cancer center from Januar..
