Objectives—The aim of this study was to evaluate the application of shear waveelastography (SWE) in the routine management of thyroid nodules, as a possibleadditional tool to the standard sonographic triage.Methods—A total of 248 consecutive patients scheduled for ultrasound-guidedthyroidfine-needle aspiration were included in the study. The presence of a purecolloid lesion was an exclusion criterion. Absolute and relative SWE stiffnessmeasurements on color-coded elastograms, expressed in kilopascals and metersper second, were correlated with radiologic and pathologic features.Results—SWE values in thyroid nodules were significantly higher than normalthyroid tissue (P= .0001), proving the different elastic properties of the patho-logic tissues.

Abstract

Objectives—The aim of this study was to evaluate the application of shear waveelastography (SWE) in the routine management of thyroid nodules, as a possibleadditional tool to the standard sonographic triage.Methods—A total of 248 consecutive patients scheduled for ultrasound-guidedthyroidfine-needle aspiration were included in the study. The presence of a purecolloid lesion was an exclusion criterion. Absolute and relative SWE stiffnessmeasurements on color-coded elastograms, expressed in kilopascals and metersper second, were correlated with radiologic and pathologic features.Results—SWE values in thyroid nodules were significantly higher than normalthyroid tissue (P= .0001), proving the different elastic properties of the patho-logic tissues. Regarding the radiologic characteristics of the nodules, SWE high-est values were associated with the largest lesions (P= .0105) but independentfrom sonographic and Dopplerfindings. The SWE elasticity was not influencedby the characteristics of the biopsy smears. Thefinal correlation between theSWE results and the pathologic diagnoses showed a trend in stiffness fromtender tumors (follicular adenoma) to papillary thyroid carcinoma (P= .016).Conclusions—SWE allows the identification of nodules within normal paren-chyma; however, the present study does not confirm the potential role in differ-entiating between benign and malignant thyroid nodules.
