目的：探讨超声造影联合超声弹性成像在甲状腺微小癌诊断中的应用价值。方法分析34例甲状腺结节患者的常规超声，超声造影和弹性成像的图像信息并与病理组织学检查相对比，评估使用上述一种方法及联合使用超声造影及弹性成像诊断的效果。结果34个甲状腺结节中，病理活检证实恶性病灶18个，良性病灶16个。弹性成像中恶性结节与良性结节的 SR，两者差异有统计学意义（P ＜0．05），ROC 曲线下面积（AUC）0．911。甲状腺微小癌超声造影具有造影剂晚进、向心性进入，瞬时低增强的特点。超声造影联合弹性成像诊断的灵敏度、特异度、诊断准确率、阳性预测值及阴性预测值分别为94．44％，87．50％，91．18％，94．44％，93．33％。结论超声造影与弹性成像联合应用对于甲状腺微小癌具有较高的临床价值。

Objective To evalue the application of contrast-enhanced ultrasound angiography and ultrasonic elastog-raphy in diagnosing thyroid microcarcinoma (TMC).Methods Totalthyroid nodules in 34 patients were detected,their contrast-enhanced ultrasound angiography,ultrasonic elastography findings and histopathology were compared and ana-lyzed,the result was calculated.Results All these thyroid nodules 18 malignant lesions and 16 begign lesions which were confirmed by biopsy.Strain ratio of malignant nodules and benign nodules in elastography,the differences of the two has statistical significance(P <0.05),ROC area under curve(AUC)0.911.Ultrasound angiography in diagnosing thyroid microcarcinoma has the characteristics of contrast medium in late,centripetal entry and instantaneous low en-hancement.The sensitivety,specificity,incidence of accuracy,positive predicitive value and the negative predicitive value of ultrasound angiography and ultrasonic elastography were 94.44%,87.50%,91.18%,94.44%,93.33%.Conclusion Both CEUS and UE have high value in thyroid microcarcinoma.
