Shear Wave Elastography May Add a New Dimension to Ultrasound Evaluation of Thyroid Nodules: Case Series with Comparative Evaluation
Figure 3
A colloid nodule in a patient with nodular goiter and papillary carcinoma. (a) on supersonic shear wave elastography (upper image) the colloid nodule (full circle) is very soft with punctuate increased stiffness (arrow head) representing microcalcifications (some not visible on B-mode lower image), in contrast to bigger high echogenicity foci (arrow), which are soft and represent inspissated colloid as evident on subsequent images. (b) presents comet tail artifacts (arrow heads) that change the direction with steering of ultrasound beam (c) indicating the nature of this artifact that is attributable to inspissated colloid in thyroid nodule.
