Abstract

The aim of this chapter is to introduce the role of computed tomography (CT) and magnetic resonance imaging (MRI) in patients with endocrine diseases of the neck region.

The role of CT in thyroid disorders is mainly limited to presurgical evaluation to assess the extent of the disease, substernal components, or relationship with extrathyroidal structures. MRI is generally used for specific indications, including the evaluation of substernal goiters and their relation to other structures.

CT and MRI are usually less sensitive than ultrasonography and scintigraphy in detecting hyperfunctioning parathyroid glands. Hybrid tomographic SPECT/CT and four-dimensional CT could be useful alternatives in detecting hyperfunctioning parathyroid glands when previous imaging methods are inconclusive.

In head and neck paragangliomas, accurate diagnosis is usually made by clinical examination together with MRI and hybrid morphological and functional imaging studies, including PET/CT with different tracers.
