摘　　要：目的评估甲状腺结节的彩色多普勒超声血供程度与弹性评分的相关性。方法入选405个行术前超声检查且术后病理资料完整的甲状腺结节,评估其彩色多普勒的血供程度及弹性评分。根据病灶区域同周围甲状腺组织血流信号比较情况,将血供程度分为Ⅰ~Ⅲ级。根据表示组织软硬程度的颜色的不同,将弹性评分分为1~4分。经统计学处理后,分析血供程度与弹性评分之间的关系。结果纳入研究的甲状腺结节中,良性结节154个,恶性结节251个。结节的血供程度与弹性评分有关（χ2=63.3,P〈0.000 1）;良性及恶性结节的血供程度与弹性评分均有关（χ2=15.8,P〈0.000 1;χ2=42.0,P〈0.000 1）。血供程度分级后,弹性评分的诊断效能在Ⅰ、Ⅱ、Ⅲ级间的差异无统计学意义（χ2=2.8,P=0.09）。结论甲状腺结节的血供程度与弹性评分具有相关性,与结节的良恶性无关。Objective To evaluate the correlation between the blood supply of thyroid nodules according to the color Doppler ultrasound image and elastography score. Methods A total of 405 thyroid nodules that underwent preoperative ultrasound examinations and had complete postoperative pathological files were selected and their blood supply and elastography scores were evaluated. The blood supply was classified into level I to Ⅲ according to the difference of blood flow signal between adjacent normal thyroid tissue and lesion. The elastography scores were from 1 to 4 according to the color that indicated the degree of tissue＇ s hardness. The correlation between blood supply and elastography score was analyzed after the data was statistically processed. Results Among all selected thyroid nodules, 154 of them were benign nodules and 251of them were malignant nodules. The blood supply was correlated with the elastography score （X2 =63.3, P〈0. 000 1）. The blood supply of benign and malignant nodules was correlated with the elastography score （X2 =15.8, P〈0. 000 1; X2 =42.0, P〈0. 000 1）. The differences of diagnosis performance of elastography scores of level I , Ⅱ, and Ⅲ were not statistically significant after the blood supply was classified （ X2 = 2.8, P = 0.09）. Conclusion The blood supply of thyroid nodules is correlated with the elastography score regardless of thyroids are benign or malignant.
