“…Decreased or absent Tc-99m trapping can be explained by the decreased activity of follicular cells due to inflammation, lymphokines produced in the thyroid subsequent to inflammation [24], or reduced levels of serum TSH following destruction-induced thyrotoxicosis. Ill-defined hypoechogenicity in the inflammed area has also been well documented [14,15] and is considered a characteristic finding in this disorder.…”

“…The US and scintigraphy images were interpreted by four When incidental findings were obtained that were significant but not inconsistent with the initial diagnosis, these were scored separately as "additional findings". Typical US and scintigraphic findings which convinced us of classifying as score 3 are demonstrated in Table 2 [ [4][5][6][7][8][9][10][11][12][13][14][15]. Fine needle aspiration biopsy (FNAB) was performed with a 21-gauge needle, which was inserted into the palpable nodule.…”

Abstract. This prospective study was designed to evaluate the potential contributions of high resolution ultrasonography (US) and Tc-99m scintigraphy in the routine diagnosis of thyroid disease. The diagnostic impacts of US and Tc-99m scintigraphy results in 177 patients visiting our thyroid clinic were assessed and scored according to the following criteria: when the information provided by either test supported, confirmed or changed the initial clinical diagnosis, they received scores of 2, 3 and 4 respectively, while score 1 was given when the test itself was useless for the differential diagnosis. US identified focal lesions that both palpation and scintigraphy had failed to detect in 14 (12.1%) of 116 patients with diffuse thyroid diseases, suggesting the necessity of routine US examinations in such patients. US scored higher than scintigraphy in the diagnosis of Hashimoto's thyroiditis, adenoma, adenocarcinoma and adenomatous goiter, and vice versa in the diagnosis of hyperthyroid and euthyroid Graves' diseases. Thus, the advantages of US over scintigraphy for morphological evaluation were confirmed. US was particularly useful for the differential diagnosis of adenomatous goiter from Hashimoto's thyroiditis or a single nodular disease. In contrast, scintigraphy gave functional images, being especially helpful for the differential diagnosis of thyrotoxicosis.

“…During the active phase of subacute thyroiditis, the ultrasound is characterized by a severely reduced thyroid echo-density that returns to a normal pattern with healing. 27 Ultrasound may offer useful information in some patients with Hashimoto's thyroiditis who have low echogenicity (see Fig. 79-7).…”
