The Value Of Acoustic Radiation Force Imaging Method Combined With Micropure On Diagnosis Of Thyroid Nodules

Objective To investigate the value of the acoustic radiation force imaging (ARFI) combined with Micropure technology used for diagnosis of benign and malignant thyroid nodules.Methods Sixty-two cases with thyroid nodules were examined with gray scale imaging, micropure technology and ARFI respectively before operation, taking pathological results as golden standard. Sensitivity and specificity, PPV,NPV of two-dimensional ultrasound, ARFI, ARFI combined with Micropure method in diagnosing benign and malignant thyroid nodules were calculated respectively.Result The sensitivity, specificity, PPV, NPV for two-dimensional ultrasound in diagnosing benign and malignant nodules were 73.68%,79.69%,51.58% and 91.07% ARFI were 84.21%,85.94%, 64.00%,94.83% and ARFI combined with Micropure were 94.74%,78.13%,54.55%,98.00% respectively.Conclusions ARFI combined with Micropure have highly clinical application value foe differentiation of benign and malignant thyroid nodules.
