Abstract:
Objective To investigate and compare the clinical value of the elastic grades score evaluation method and ultrasound elasticity imaging strain ratio method in identifying thyroid nodules.Methods A total of 120 cases confirmed by operation and pathology of the patients with thyroid nodules in our hospital were underwent ultrasound elasticity imaging detection,the thyroid nodules were identified with the elastic grades score evaluation method and ultrasound elasticity imaging strain ratio method respectively,and were compared with pathological results separately.Results The sensitivity,specificity and accuracy rate were 79.4％,81.3％,81％ with the elastic grades score evaluation method,the sensitivity,specificity and accuracy rate were 91.2％,90.3％,93.3％ with ultrasound elasticity imaging strain ratio method,of which was significantly higher with ultrasound elasticity imaging strain ratio method than with the elastic grades score evaluation methodby statistical analysis(x2 =28.170,P =0.000;x2 =34.219,P =0.000; x2 =17.928,P =0.000).Conclusion Ultrasound elastography strain ratio and rating score evaluation method can be used as an effective method in differentiating malignant from benign thyroid nodules,which can effectively improve the accuracy rate of the differential diagnosis of thyroid nodules and effectively remedy the diagnostic error band to cognitive differences with traditional ultrasound evaluation.The method of ultrasound elastography strain rate ratio was better with advantages of easy to operate,easy to learn and master,and easily accepted by patients,which is worthy of clinical application.
