Role of Imaging in Thyroid Disease
The diagnosis of specific thyroid disorders is currently carried out with magnetic resonance imaging (MRI), computed tomography (CT), radioiodine scintigraphy and positron emission tomography (PET) scanning, as well as ultrasound. Each of these imaging modalities has specific indications, which have changed considerably over the past decade. Specifically, radioiodine scintigraphy, although still an invaluable tool in the differential diagnosis of hyperthyroidism, has lost some of its importance and has been replaced by ultrasonography, particularly in the diagnostic work-up of thyroid nodules and the follow-up of patients with thyroid cancer. This chapter discusses the contribution of the various imaging techniques in the context of specific thyroid disorders in adults.
