[The normal thyroid gland in the scintigram: size and form variants, thyroid dystopia]

Quantitative data about the size of the normal thyroid gland are presented: height, width and area of the right and left lobe are scintigraphically different. The calculated weight varies depending on the correction factor. Displaced thyroid tissue is found in the center line, whereas iodine accumulating tissue located in the lateral neck should lead to a suspicion of carcinoma.
