“…The nonspecific ultrasonographic findings seen in HT complicate follow-up by making it more difficult to assess tumor size or identify other areas of concern within the thyroid both at presentation and during follow-up (28,29). Furthermore, HT often leads to atypical cervical lymphadenopathy (30), which makes it more difficult to exclude locoregional metastasis confidently.…”

“…Comparison of values for conventional US and USE indicated an increase in sensitivity from 85.7% to 92.9%, and specificity from 79.6% to 94.4%, respectively. USE findings corresponded with the cytological results, suggesting that elastography may reduce the frequency of unnecessary FNAB [47].…”

“…USE may demarcate nodules and pseudonodules, by evaluating tissue stiffness. Yildirim et al compared the utility of USE, US and FNAB in differentiating between true nodules and pseudonodules in 54 patients with Hashimoto's thyroiditis [47]. The patients were subcategorised into three groups according to their grey scale US findings: patients with non-demarcated hypoechogenic focal areas (34); patients with demarcated hyperechogenic focal areas (12); and patients with demarcated hypoechogenic nodular lesions (9).…”

“…Yildirim i wsp. porów-nali przydatność USE, USG i BACC w różnicowaniu między prawdziwymi guzkami i pseudoguzkami, u 54 pacjentów z CAT [47]. Pacjentów podzielono na trzy grupy, w zależności od wyników badania ultrasonograficznego: pacjenci z niewyraźnie odgraniczonymi hipoechogenicznymi zmianami ogniskowymi (34 pacjentów), pacjenci z wyraźnie odgraniczonymi hyperechogenicznymi zmianami ogniskowymi (12 pacjentów) oraz pacjenci z wyraźnie odgraniczonymi hipoechogenicznymi zmianami guzkowymi (9 pacjentów).…”

Sonoelastography (USE) is a constantly evolving imaging technique used for the noninvasive and objective estimation of tissue stiffness. Several USE methods have been developed, including Quasi-Static or Strain Elastography and Shear Wave Elastography. The utility of USE has been demonstrated in differentiating between malignant and benign thyroid lesions. Recently, USE has been applied in the evaluation of thyroiditis and autoimmune thyroid disease (AITD). Thyroid inflammatory illnesses constitute a diverse group of diseases and may manifest various symptoms. These conditions may share some parallel clinical, biochemical, and ultrasonographic features, which can lead to diagnostic difficulties. USE may be an additional tool, supporting other methods in the diagnosis and treatment monitoring of thyroid diseases, other than thyroid nodular disease. The aim of this article was to analyse and summarise the available literature on the applicability of different elastographic techniques in the diagnosis, differentiation and monitoring of various types of thyroiditis and AITD. Advantages and limitations of this technique are also discussed. StreszczenieSonoelastografia (USE) jest stale rozwijającą się techniką obrazowania stosowaną do nieinwazyjnej i obiektywnej oceny sprężystości tkanki. Jak dotąd opracowano wiele metod USE, które można podzielić na dwie zasadnicze grupy: quasi-statyczną elastografię i elastografię fali poprzecznej (SWE). Wykazano wysoką skuteczność USE w różnicowaniu łagodnych i złośliwych zmian ogniskowych w gruczole tarczowym. Coraz częściej USE znajduje zastosowanie w ocenie zapaleń gruczołu tarczowego, w tym autoimmunologicznej choroby tarczycy (AITD). Zapalne choroby tarczycy stanowią bardzo zróżnicowaną grupę chorób, których wczesne objawy są nieswoiste. Trudności diagnostyczne mogą wynikać zarówno ze wspólnych cech klinicznych, biochemicznych, jak i ultrasonograficznych zapaleń tarczycy. Sonoelastografia może być uznana za dodatkowe narzędzie, wspierające inne stosowane metody w diagnostyce i monitorowaniu leczenia chorób tarczycy innych niż choroba guzkowa tarczycy. Celem niniejszego artykułu była analiza i podsumowanie dostępnej literatury na temat możliwości zastosowania technik elastograficznych w rozpoznawaniu, różnicowaniu i monitorowaniu różnych typów zapalenia gruczołu tarczowego. Przedstawiono zarówno wady, jak i zalety stosowania tej techniki w chorobach tarczycy. (Endokrynol Pol 2014; 65 (6): 520-531)

“…SWE will continue being the problem solver not only with the risk categorization using the shear wave velocity (SWV) values, but with many other aspects, i.e. comparing the SWE color coded maps of the normal parenchyma and the lesions [21] Sometimes the stiffness of the nodule can be graded using the VTI maps and the risk of malignancy and a possible lymph node metastasis can be predicted [22]. SWE can sometimes present more useful and problem-solving data in the categorization of the thyroid nodules with nondiagnostic grey-scale US findings.…”

The aim of this paper is to review the radiological evaluation of thyroid nodules detected with ultrasonography (US), thoroughly and in harmony with the clinical-endocrinological-surgical management. In this review, we tried to summarize the radiological evaluation of nodules detected in the thyroid in compliance with recently published and accepted guidelines, including the most advanced sonographic protocols, emphasizing the indications of crosssectional imaging when needed. In this review important aspects were demonstrated with tables, illustrations and take-home points and technical aspects were emphasized with images and diagrams. We believe that this review, which is concluded with an extensive summary with the support of most recent sources, is an up-to-date and comprehensive evaluation of the broad spectrum of thyroid nodule radiology. We think that the management of any kind of nodule that can be encountered during the US examination can be done successfully by going through the paths described in the pictures, tables and texts in this article.
