“…Although elastography cannot replace conventional US, when performed together (elastography plus US), the sensitivity and specificity of the assessment improve (32). In addition, the instances in which elastography might be clinically decisive when combined with US must still be established as well as its limitations and potential means of minimizing these limitations (33).…”

Thyroid nodules are frequent findings, especially when sensitive imaging methods are used. Although thyroid cancer is relatively rare, its incidence is increasing, particularly in terms of small tumors, which have an uncertain clinical relevance. Most patients with differentiated thyroid cancer exhibit satisfactory clinical outcomes when treatment is appropriate, and their mortality rate is similar to that of the overall population. However, relapse occurs in a considerable fraction of these patients, and some patients stop responding to conventional treatment and eventually die from their disease. Therefore, the challenge is how to identify the individuals who require more aggressive disease management while sparing the majority of patients from unnecessary treatments and procedures. We have updated the Brazilian Consensus that was published in 2007, emphasizing the diagnostic and therapeutic advances that the participants, representing several Brazilian university centers, consider most relevant in clinical practice. The formulation of the present guidelines was based on the participants' experience and a review of the relevant literature.

Embora o câncer seja proporcionalmente raro, sua incidência vem aumentando, especialmente de tumores pequenos, cuja evolução clínica é incerta. A maioria dos pacientes com carcinoma diferenciado de tireoide evolui bem quando adequadamente tratada, com índices de mortalidade similares à população geral. Por outro lado, um percentual não desprezível apresenta recidivas e alguns eventualmente não respondem às terapias convencionais, evoluindo para óbito. Assim, o desafio é distinguir os pacientes merecedores de condutas mais agressivas e, ao mesmo tempo e não menos importante, poupar a maioria de tratamentos e procedimentos desnecessários. Atualizamos o Consenso Brasileiro publicado em 2007, ressaltando os avanços diagnósticos e terapêuticos que os participantes, de diferentes Centros Universitários do Brasil, consideram mais relevantes para prática clínica. A elaboração dessas diretrizes foi baseada na experiência dos participantes e revisão da literatura pertinente. Arq Bras Endocrinol Metab. 2013;57(4):240-64 Descritores

“…The two score scale (table V) produced better performance for nodules less than 2 cm in diameter [57]. Elastography is not suited for nodules with a diameter less than 5 mm [21,24] although the exact lower limit of the diameter for RTE usability is not known [9]. It is also unsuitable for nodules larger than 3 cm as the nodule cannot be encompassed by the image [9,38].…”

“…Basically, two main approaches for elastography of the thyroid are used in clinical practice: strain and shearwave elastography [8][9][10][11] (fig 1). Most of the times, offline analysis of the information is performed in experimental, work-in-progress models or on prototypes while machines for clinical applications use online signal processing.…”

Thyroid elastography has become, lately, one of the main focuses in thyroid imaging. With more than one hundred papers published on this subject, the core of accumulated knowledge justifies the need for a comprehensive review on the topic. The paper presents the various elastographic techniques used for thyroid assessment. Both strain and shear wave elastography, with all their variants, are discussed. Thereafter the paper proceeds to a detailed description of the technical peculiarities, diagnostic value, limitations and pitfalls for each technique. Although the main accent is placed on thyroid nodules, the applications of elastography in other thyroid disease, diffuse or focal, are also presented. The results of the available metaanalyses are reviewed and the proven value of the technique is highlighted. Still unanswered questions and directions for future research are emphasized, whenever appropriate.

Accurate differentiation of focal thyroid nodules (FTL) and thyroid abnormalities is pivotal for proper diagnostic and therapeutic work-up. In these two part articles, the role of ultrasound techniques in the characterization of FTL and evaluation of diffuse thyroid diseases is described to expand on the recently published World Federation in Ultrasound and Medicine (WFUMB) thyroid elastography guidelines and review how this guideline fits into a complete thyroid ultrasound exam.
