Abstract
Thyroid imaging modalities include both morphological and functional imaging methods, sometimes combined in hybrid devices. Ultrasonography allows estimation of thyroid size, evaluation of its morphology, and examination of lymph nodes in thyroid cancer patients. Nuclear medicine techniques are an integral part of the work-up of thyrotoxicosis, thyroid nodules, and thyroid cancer. Finally, computed tomography and magnetic resonance imaging play an adjuvant role in the evaluation of thyroid disease and are especially useful in evaluating regional lymphadenopathy, assessing loco-regional extension of the tumor, spread of disease into the mediastinum or retro-tracheal region, and detecting pulmonary and hepatic metastases.
