Shear Wave Elastography May Add a New Dimension to Ultrasound Evaluation of Thyroid Nodules: Case Series with Comparative Evaluation
Figure 1
Diffuse sclerosing papillary carcinoma of the left lobe of the thyroid gland (arrow) in patient with multinodular goiter and multiple colloid nodules (arrow head). (a) on B-mode ultrasound (lower image), the cancer is less suspicious than some of the colloid nodules; however, on supersonic shear wave elastography (upper image) the nodule presents areas of high stiffness (over 75 kPa) indicating malignant lesion. The colloid nodule presents as a lesion with low stiffness. (b) on strain elastography, the carcinoma qualitatively and quantitatively presents features of soft lesion falsely indicating benign nature of the lesion.
