目的比较超声弹性成像与常规彩超检查在甲状腺结节中的诊断价值。方法选取医院行甲状腺手术治疗的患者240例,术前均采用超声弹性成像与常规彩超检查,与术后病理结果比较,比较2种方法检查的敏感性、特异性和准确率。结果术后病理证实恶性结节患者37例,良性结节患者203例。2种检查方法比较,常规彩超检查的敏感性为70.3%,特异性为95.1%,准确性为91.3%;弹性成像敏感性为89.2%,特异性为98.0%,准确性为96.7%。超声弹性成像在诊断敏感性方面要优于常规彩超检查(P<0.05)。结论超声弹性成像对甲状腺结节的诊断敏感性更高,更能识别结节的良恶性。
Objective To compare the diagnostic value of ultrasound elastography and routine color Doppler ultrasound in thyroid nodules. Methods A total of 240 patients undergoing thyroidectomy in our hospital were enrolled. All patients underwent preoperative ultrasound elastography and conventional color Doppler echocardiography. Compared with the postoperative pathological results, the sensitivity, specificity and accuracy of the two methods were compared. Results Postoperative pathology confirmed 37 cases of malignant nodules, 203 cases of benign nodules. The sensitivity of conventional color Doppler ultrasound examination was 70.3%, the specificity was 95.1% and the accuracy was 91.3%. The sensitivity of elastography was 89.2%, the specificity was 98.0% and the accuracy was 96.7%. Ultrasound elastography in the diagnosis of sensitivity than conventional color Doppler ultrasound examination (P <0.05). Conclusion Ultrasound elastography is more sensitive to the diagnosis of thyroid nodules and better to identify the benign and malignant nodules.
