摘　　要：目的利用彩色多普勒血流显像(CDFI)研究甲状腺实性结节的血流分布模式及结节内血流的动静脉比例,探讨CDFI在甲状腺实性结节良恶性鉴别诊断中的价值。方法对112例共131个甲状腺实性结节或以实性为主结节术前进行CDFI检查,观察并比较良恶性结节的血流分布模式及结节内血流的动静脉比例有无差异,评价结节内血流的动静脉比例对甲状腺实性结节良恶性鉴别诊断的价值。结果在血流分布模式方面,恶性结节的以中央型为主,良性结节以周边型及混合型为主,差异有统计学意义(P<o.05);在动静脉比例方面,恶性结节内血流以动脉型占多数,良性结节内多表现为静脉型或混合型,差异有统计学意义(P<0.05);结节内动脉型血流比例预测甲状腺恶性结节的准确度高于中央型血流分布模式对恶性结节的诊断。结论 CDFI检测结节内动静脉血流比例对甲状腺实性结节良恶性的鉴别诊断具有一定价值。Objective To evaluate the value of Color Doppler Flow Imaging（CDFI） in differentiating benign. from malignant thyroid solid nodules by studying the flow pattern and artery-to-vein ratio of the nodules. Methods 112 pa- tients（a total of 131 nodules） with thyroid solid nodules or mainly solid nodules were examined by CDFI. Analyzed differences of the flow pattern and artery-to-vein ratio between benign and malignant nodules and evaluated the differ- ential diagnostic value of artery-to-vein ratio in nodules. Results CDFI with blood flow patterns showed statistical sig- nificance（P〈0.05） between benign and malignant thyroid nodules. Mixed and peripheral flow patterns were observed in the majority of benign nodules, while internal oriented flow pattern in the malignant thyroid nodules. The blood flow in artery-to-vein ratio of malignant nodules had the artery type of the majority while benign nodules with vein type or mixed type were in the majority and these two g^oups were markedly different（P〈0.05）. Nodules within the arterial ratio for prediction of malignant thyroid nodules are more accurate than those of internal oriented flow pattern. Conclu- sions The artery-to-vein ratio in nodules was available for differential diagnosis of benign and malignant thyroid solid nodules.
