High-resolution real-time ultrasonography of thyroid nodules.
High-resolution real-time ultrasonography was used to evaluate 98 patients with palpable abnormalities of the thyroid and positive isotopic studies. It confirmed 37 of 73 (51%) suspected solitary nodules. Of 25 patients thought to have multinodular goiter, sonography was supportive in 21 (84%). In patients with adenoma or adenomatous nodules, characteristic features included a sonolucent "halo". Colloid nodules tended to be more sonolucent than normal thyroid tissue, whereas Hashimoto thyroiditis was characterized by an enlarged gland and decreased echogenicity.
