Shear Wave Elastography May Add a New Dimension to Ultrasound Evaluation of Thyroid Nodules: Case Series with Comparative Evaluation
Figure 2
A benign nodule (arrow) of the left lobe of the thyroid gland (with massive degeneration demonstrated on contrast-enhanced ultrasound and in pathologic examination) in patient with multinodular goiter. (a) on B-mode axial section, the nodule is markedly hypoechoic, taller than wide, with somewhat ill-defined margins and high echogenic foci suggesting microcalcifications, a suspicious nodule. (b) on strain elastography, the nodule both qualitatively and quantitatively presents as very hard suspicious of cancer. (c) on supersonic shear wave elastography (upper image), the lesion is very soft, truly indicating its benign nature, with some stiff calcifications in the capsule.
