New High-Resolution Ultrasound Evaluation of Diseases of the Thyroid Gland

Ultrasonography for thyroid screening after head and neck irradiation in childhood cancer survivors

“…Recent reviews have demonstrated that its sensitiv-also is cost-effective, costing about half that of a 99m Tc thyroid scan. ity for detecting thyroid parenchymal abnormalities far exceeds that of clinical examination or thyroid scintigraUltrasound has greatly facilitated fine-needle aspiration (FNA) biopsy of thyroid lesions, particularly those phy [26][27][28][29][30][31][32][33]. The normal thyroid gland typically shows homogeneous intermediate echogenicity.…”

“…The high prevalence of inhomogeneity in our population (44%) may represent nign nodules). These inaccuracies presumably are due to inadequate sampling or sampling error [26,[29][30][31][32][33]35]. an acceleration of normal thyroid aging or may be induced by radiotherapy.…”
