• El Ultrasonido de tiroides realizado por un Radiólogo Experto y con un equipo de Alta Resolución, puede diferenciar entre nódulos benignos y malignos.
• El uso de la ELASTOGRAFIA por ultrasonido, es un nuevo método con resultado aun controversiales en el diagnóstico de Cáncer, porque algunos canceres como el folicular, medular, se confunden con nódulos hiperplásticos y adenomas foliculares.
• La Elastografía cuantifica la elasticidad del tejido y su valor diagnostico potencial es que los canceres producen “endurecimiento” del tejido, se utiliza un Score de 4 grados:
I: Suave, elasticidad generalizada.
II: Mayormente suave, elasticidad en la mayor parte del nódulo.
III: Mayormente firme, endurecimiento en la mayor parte.
IV: Firme, endurecimiento total.

Thyroid nodule ultrasound: technical advances and future horizons
Insights Imaging 2015; 6: 173-188
Abstract
Thyroid nodules are extremely common and the vast majority are non-malignant; therefore the accurate discrimination of a benign lesion from malignancy is challenging. Ultrasound (US) characterisation has become the key component of many thyroid nodule guidelines and is primarily based on the detection of key features by high-resolution US. The thyroid imager should be familiar with the strengths and limitations of this modality and understand the technical factors that create and alter the imaging characteristics. Specific advances in high-resolution US are discussed with reference to individual features of thyroid cancer and benign disease. Potential roles for three-dimensional thyroid ultrasound and computer-aided diagnosis are also considered. The second section provides an overview of current evidence regarding thyroid ultrasound elastography (USE). USE is a novel imaging technique that quantifies tissue elasticity (stiffness) non-invasively and has potential utility because cancers cause tissue stiffening. In recent years, there has been much research into the value of thyroid USE for distinguishing benign and malignant nodules. Preliminary findings from multiple pilot studies and meta-analyses are promising and suggest that USE can augment the anatomical detail provided by high-resolution US. However, a definite role remains controversial and is discussed.
