Study Summary
Shear wave ultrasound elastography is a new technique of finding the softness or hardness in tissue by applying a "push" generated by the machine. This technique will help in diagnosing malignancy in the thyroid gland without biopsy and avoiding biopsy in noncancerous nodules.

Experimental Treatment
Group I: SWUS ElastographyExperimental Treatment1 Intervention
This is a noninvasive technique using focused ultrasonic beams (pushing beams.) Several pushing beams at increasing depths are transmitted to generate a quasi-plane shear wave frame that propagates throughout the imaging area. After generating the shear wave, an ultrafast imaging sequence is performed to acquire successive raw radiofrequency dots at a very high frame rate (up to 20,000 per second). A tissue elasticity assessment can be derived from shear wave propagation speed. A color-coded image is displayed; softer tissue in blue and stiffer tissue in red. Quantitative information is delivered by drawing regions of interest on the thyroid and surrounding tissues which is the Elasticity Index expressed in kilo-Pascal (kPa). Due to the lack of manual compression and known value of the strength of pushing beam, SWUS gives an objective number to stiffness within the nodule.
