Abstract

Ultrasonographic elastography is a quantitative assessment of tissue consistency, it is used to assess the stiffness of several tissues and has recently been used for the evaluation of thyroid nodules. In view of the need for further studies on the topic, the aim of the present study was to assess the accuracy of thyroid elastography in predicting malignancy. To achieve the proposed objectives, a prospective cohort study was carried out that included patients with thyroid nodules submitted to FNAB. The sensitivity and specificity of elastography in the prediction of malignant findings was estimated. 43 patients were included in the study. The% AR showed a significant correlation with the findings of histopathology and showed a high discriminatory capacity, demonstrated by AUC-0.968. For the suggested cutoff point, sensitivity values ​​equal to 100% and specificity 84% were found.
