Shear Wave Elastography May Add a New Dimension to Ultrasound Evaluation of Thyroid Nodules: Case Series with Comparative Evaluation

Figure 5

An artifact (arrow) from tissue compression on elastogram (upper image) in patient with Hashimoto thyroiditis, with no real focal lesions evident on B-mode ultrasound (lower image). A hard stiff pseudolesion is generated (see also Supplementary material 1 available online on doi: 10.1155/2012/657147). To avoid such artifacts no pressure on the probe during elasticity evaluation should be applied.
