Abstract

In diffuse or nodular euthyroid goiter, diagnostic imaging is indicated to define, by sonography, the morphology, size and structure of the goiter and to evaluate, by scintigraphy, the regional thyroid function. The instrumental diagnosis of thyroid nodule is essentially based on sonography, scintigraphy and (US-guided) needle aspiration cytology. The evaluation of some sonographic findings (echogenicity, calcification, lesion margins and presence of peripheral ring) may direct to the differentiation of a benign or malignant lesion. The role of color Doppler in the characterization of thyroid nodules is still controversial. Scintigraphy provides information on nodular function, being also the only exam able to show the presence of autonomously functioning thyroid tissue ('hot' nodule), whose diagnosis allows to rule out the presence of thyroid carcinoma with a very strong probability. In intrathoracic goiter, CT and MRI are indicated to show the continuity with the cervical thyroid and to define the relationships with adjacent structures. Radioiodine scintigraphy shows with high (>90%) diagnostic accuracy the thyroid nature of a mediastinal mass (plunging goiter).
