“…Thyroid US: technological advances over four decades US evaluation for thyroid imaging was introduced in the late 1960s and early 1970s (5,6,7,8,9,10,11). The A-mode (amplitude mode) thyroid scan allows distinction between solid and cystic lesions and the measurement, with reasonable accuracy, of the dimensions of the thyroid gland and of medium-sized thyroid nodules (9,12).…”

“…In 1967, Fugimoto et al (6) first described the B-mode (brightness mode) imaging technique and the US patterns generated by nodular areas within the thyroid gland. Thyroid tissue was defined either as 'cystic', 'sparsely spotted' or 'malignant' on the basis of the quantity and degree of attenuation of the echoes produced by the lesions crossed by the US beam (6). In 1974, the advent of the 'gray-scale' display offered a real-time creation of easyto-read images, enabling a more accurate differentiation between benign and malignant nodules and a precise measurement of thyroid volumes (13,14,15).…”

In patients with thyroid nodules, ultrasound (US) imaging represents an indispensable tool for assessment of the risk of malignancy. Over approximately four decades, innovative technology and successive improvements have facilitated its entry into the routine management and greatly improved its predictive value. When US features cannot reliably rule out thyroid cancer, US guidance allows a correct and safe sampling also of small or deeply located thyroid lesions. Obtained in this way, cytological or microhistological specimens may reliably define the nature of most thyroid nodules, and the information from histochemical or molecular markers shows promise in the classification of the remaining indeterminate cases. While a prompt surgical treatment can be offered in the minority of suspicious or definitely malignant cases, most individuals warrant only a follow-up. However, at initial evaluation, or over the years, a fraction of these benign lesions may grow and/or become symptomatic. Such cases may benefit from US-guided minimally invasive procedures as an alternative to surgery. Image-guided percutaneous treatments most often achieve relief of neck complaints, are inexpensive, and can be performed on an outpatient basis. The risk of major complications, after adequate training, is very low. Importantly, thyroid function is preserved. Currently, percutaneous ethanol injection for cystic lesions and thermal ablation, with laser or radiofrequency, for solid nodules are increasingly used and disseminated beyond the initial core facilities. In centres with expertise and high patient volume, their use should be considered as first-line treatment alternatives to surgery for selected patients with benign enlarging or symptomatic thyroid lesions.

“…A ultra-sonografia tem se mostrado um método acurado para determinar o volume da tiróide, desde a sua introdução como método diagnóstico, na década de 60 (12). Com os equipamentos de última geração e transdutores de alta resolução, essa técnica começou a ser amplamente usada também para detecção e caracterização de nódulos tiroideanos (13).…”

RESUMOO objetivo deste trabalho foi estudar a prevalência de bócio e nódulos em uma população com mais de 50 anos, comparando-a com grupo controle composto pelos filhos. Para isso, foram avaliados 101 indivíduos (19M / 82 F) com idades entre 51 e 85 anos e 65 filhos (18 M / 47 F) com idades entre 14 e 50 anos. Utilizamos o ultra-som para diagnóstico de bócio e nódulos, mas foi feita, também, avaliação clínica com palpação da tiróide. A prevalência de bócio e nódulos foi maior nos indiví-duos com mais de 50 anos (15,8% e 18,8%, respectivamente), do que nos filhos (3,1% e 7,7%, respectivamente), Não observamos correlação entre volume tiroideano e idade. A palpação da tiróide se mostrou pouco sensível para detecção de bócio e nódulos, mas com alta especificidade. Concluímos que a prevalência de bócio e nódulos é maior na população com mais de 50 anos, embora sem correlação entre volume tiroideano e idade. O ultra-som se mostrou melhor que a palpação isoladamente, na detecção de alterações do volume e presença de nódulos tiroideanos. ABSTRACTThe aim of this study was to determine the prevalence of goiter and thyroid nodules in a population aged 50 years and older, matching with a younger control group, their offspring. We studied 101 subjects (19M/82F), 51 to 85 years and 65 offspring (18M / 47F), 14 to 50 years of age. Ultrasound was used to identify goiter and thyroid nodules, but all thyroids were also evaluated by palpation. The prevalence of goiter and thyroid nodules were higher in the older group (15.8% and 18.8%, respectively) as compared to their offspring (3.1% and 7,7%, respectively). No correlation was found between thyroid volume and age. Thyroid palpation has poor sensitivity but high specificity in identifying goiter and nodules. We conclude that goiter and nodules are more prevalent in the elderly, with no correlation between thyroid volume and age. Ultrasound was better than thyroid palpation to detect goiter and nodules. A MAIORIA DOS ESTUDOS PUBLICADOS concorda que, na população idosa, a prevalência de nódulos tiroideanos é nitidamente maior e tende a aumentar proporcionalmente com a idade (1-5). Por outro lado, relatos sobre o volume glandular em idosos são discordantes (1-8). A controvér-sia existe devido a alguns fatores, como: nível de suficiência de iodo alimentar na região estudada, etnia e métodos usados para a detecção destas alterações (palpação, ultra-som ou exame anátomo-patológico) que podem interferir diretamente nos resultados.
