Background: Thyroid nodules are a common finding in clinical practice. Among classic risk factors for thyroid cancer, thyroid scintigraphy has traditionally been attributed prognostic value, with cold nodules implying greater risk. However, research supporting this assumption is of considerable age and possibly influenced by selection bias. In this study, we aimed to calculate the risk of malignancy in cold and hot nodules.Material and Methods: All thyro...

Introduction: The first-line imaging modalities to locate adenomas preoperatively in primary hyperparathyroidism (PHPT) are ultrasonography (US) and subtraction scintigraphy (SuSc). When these contradict each other or are inconclusive an [11C]-methionine PET/CT (MET-PET/CT) or a 4-dimensional computed tomography (4D-CT) can be performed.Objectives: The aim of this retrospective study was to evaluate the value of MET-PET/CT in the preoperative localizatio...
