Combined PET/CT with Iodine-124 in Diagnosis of Mediastinal Micrometastases in Thyroid Carcinoma

Iodine-124 PET is an useful 3-dimensional imaging technique for diagnosis and management of thyroid diseases. The difficulty in interpretation of the PET scans with highly selective tracers like iodine-124, is the lack of identifiable anatomical structures, so an accurate anatomical localization of foci presenting abnormal uptake is problematic. Consequently, a combined PET/CT scanner can resolve these difficulties by co-registering PET and CT...
