摘　　要：目的初步探讨超声造影在甲状腺肿块诊断中的应用价值。方法26例29个甲状腺肿块术前常规二维及彩色多普勒超声检查后,行超声造影检查,观察造影剂开始显影、达峰及消退的全过程,并用ACQ软件进行时间-强度曲线分析。结果结节性甲状腺肿的超声造影表现大多以等增强、低增强为主,少数为高增强;腺瘤呈"快进慢退高增强"的造影表现,为富血供型;甲状腺癌大多以等增强及低增强为主,增强回声不均匀,早于周边甲状腺组织消退。结论超声造影对甲状腺肿块良恶性的鉴别提供了更多的信息,有一定的诊断作用。Objective To discuss the diagnostic value of contrast-enhanced ultrasound （CEUS） in the thyroid masses. Methods Twenty-six cases with 29 thyroid masses were examined by two-dimensional and color Doppler ultrasonography before operation. Following the contrast-enhanced ultrasound, we observed the beginning of contrast agent enhancement, the peak and dissipation as a whole, and analyzed the time-intensity curve with ACQ software. Results Most nodular goiter cases showed isoenhancement or hypoenhancement; few cases showed hypoenhancement; adenomas with ＂fast-in and slowlyout＂ pattern showed the rich blood supply; most thyroid cancer showed sioor hypoenhancement, uneven enhance echo, and dissipated earlier than the peripheral thyroid tissues. Conclusion Contrast-enhanced ultrasound can provide more informations for the diagnosis of benign and malignant thyroid masses.
