A thyroid nodule is a discrete lesion within the thyroid gland that is sonographically distinguishable from surrounding thyroid parenchyma.
Gray-scale and color are used to evaluate the size, location within the thyroid, and US features, which include   composition, echogenicity, regularity of the border or margin around the nodule, presence of a halo, vascular pattern, as well as presence or absence of coarse or fine calcifications.
