弹性成像与超声造影诊断桥本氏甲状腺炎合并恶性结节的临床价值

Value of ultrasonic elastography and contrast-enhanced ultrasound in diagnosing hashimoto's thyroiditis combining with malignant nodule

目的评价超声弹性成像与超声造影(CEUS)对桥本氏甲状腺炎合并恶性结节的诊断价值。方法对42例诊断为桥本氏甲状腺炎患者的95个结节分别进行超声弹性成像及CEUS检查,将超声诊断结果与病理结果进行对照。结果以弹性评分≥3分为高度恶性预测指标,超声弹性成像诊断的敏感性67.74%、特异性87.50%、准确性81.05%;以不均匀增强为恶性结节的诊断标准,则CEUS的诊断的敏感性90.32%、特异性92.19%、准确性91.57%。结论 CEUS在桥本氏甲状腺炎合并恶性结节的诊断上较超声弹性成像更有价值。

Objective To assess the value of ultrasonic elastography and contrast-enhanced ultrasound （CEUS） in diagnosing hashimoto＇s thyroiditis combining with malignant nodule. Methods 42 cases which had been diagnesed with hashimoto＇s thyroiditis with 95 tyroid nodule were received by ultrasonic elastography and CEUS.Then,the ultrasonic findings were confirmed by pathology. Results 3-4 of elastogram score was high malignancy predict indicator, the sensitivity, specificity and accuracy of ultrasonic elastography were 67.74%, 87.50%, 81.05% ; respectively, inhomogeneous enhancement was the diagnosis of malignant nodule, the sensitivity, specificity and accuracy of CEUS were 90.32%, 92.19% ,91.57%. Conclusion CEUS is more higher value than ultrasonic elastography in the diagnosis of hashimoto＇s thyroiditis combining with malignant nodule.
