摘　　要：目的探讨甲状腺结节的血流特征对其良恶性鉴别的价值。方法回顾性分析252个完全实性及接近完全实性的甲状腺结节的血流特征,根据结节大小分成<1cm组和≥1cm组。运用统计学方法分析结节的血流特征与良恶性的关系。结果良性结节以Ⅱ级血流、混合型血流为主,恶性结节则以Ⅰ级血流、边缘型和内部型血流为主。良性结节在<1cm组以Ⅰ级血流为主,在≥1cm组以Ⅱ级血流为主;恶性结节在两组中均以Ⅰ级血流为主,但随着结节增大,Ⅱ、Ⅲ级血流所占比例上升。<1cm组的良恶性结节均以边缘型血流为主,≥1cm组的良性结节以混合型为主,恶性结节以内部型为主。结论良恶性甲状腺结节的血流特征存在一定重叠性,对鉴别诊断价值有限。结节大小对血流特征虽有一定影响,但即使基于结节大小,其对鉴别结节良恶性依然没有价值。Objective To evaluate the diagnostic performance of blood flow supply features in distinguish benign from malignant thyroid nodules. Methods A total of 252 solid or almost solid thyroid nodules with histopathological results were included. Blood flow amount and blood flow type were evaluated for every nodule. Nodules were divided into two groups according to size （〈1 cm and ≥1 cm）. Results Most benign nodules showed grade II blood flow supply and peripheral type, while most malignant nodules were grade I blood flow supply, internal or mixed type. Blood flow supply for benign nodules predominantly showed grade I in 〈1cm group and grade II in ≥1cm group. While for malignant ones it mainly showed grade I in both two groups and the percentage ith grade II and grade III nodules increased along with an increased size. For blood flow type, both benign and malignant nodules mainly showed peripheral type in 〈1cm group. While in ≥1 cm group, mixed type was more frequently observed in benign nodules, and internal type more in malignant ones. Conclusions The blood flow supply features can be overlapped in benign and malignant nodules so that they are not enough for differential diagnosis. Nodule size is related to the blood flow supply features to some extent, but the relationship has no value for differentiation.
