摘要
目的探讨高频超声与彩色多普勒超声(CDFI)对甲状腺癌的诊断价值。方法对经手术病理证实的24例甲状腺癌和36例甲状腺腺瘤的高频超声图像与彩色多普勒特征进行对比分析。结果甲状腺癌的高频超声声像图多数为实性低回声肿块及无回声肿块内实质部分有沙砾状钙化或粗糙的钙化光团,少数表现为增强及杂乱回声肿块。彩色多普勒血流成像(CDFI)显示肿块内血流阻力指数较高,平均为0.70。结论应用高频超声及彩色普勒超声对甲状腺癌的诊断具有很大的临床应用及指导价值,有较高的诊断符合率。
Objective To explore the value of high-frequency ultrasonography and colour Doppler flow imaging on thyroid earcinomca. Methods 24 thyroid cainomas and 36 patients with thyroid adenoma were exminated by high-frequency and colour ultronography before operations, and they were all analyesd by surgery and pathology. Results Most of nodules in thyroid carcinoma were hypoechoic and not well-distributed with liquefaction,calcif ication like sand or calcification echogenic mass. A few were high-level echo or tangle echo. CDFI could detect an abundant blood flow signals inside. Conclusion It is highly accurate in the diagnosis of thyroid carcinoma with high -frequency ultrasound and Color Doppler flow image,and it can play an important role in clinic.
