Abstract :

INTRODUCTION:Ultrasound elastography using acoustic radiation force impulse (ARFI) is the novel technique used in oncology diagnosis. AIM: The aim of the present study objective was to evaluate the role of ultrasound elastography using ARFI quantification in characterizing and differentiating malignant versus benign thyroid nodules. METHODS: A total of 48 thyroid nodules were evaluated with conventional sonography and ultrasound elastography using ARFI quantification. The final diagnosis was obtained from histologic findings. A total of 31 malignant and 17 benign nodules were diagnosed on the basis of histologic examination. RESULTS: On ARFI quantification, the mean shear wave speed (SWS) values (M � SD) of malignant and benign thyroid nodules were 3.20�0.93 m/s and 1.66� 0.50 m/s, respectively. The diagnostic accuracy of ARFI was found to be 93.75%. CONCLUSION: ARFI as an effective diagnostic tool in characterizing and differentiating benign from malignant thyroid nodules.
