摘　　要：目的总结甲状腺结节的超声造影增强特征。方法对102例117个经手术病理证实的甲状腺实性结节进行超声造影检查,分析比较良恶性结节的造影灌注过程。结果增强早期,对比甲状腺实质,良性结节多同步或早期增强,恶性结节多延迟增强。增强达峰期,良性结节多表现为强度高于甲状腺实质、整体均匀增强和边缘增强;而恶性结节多表现为强度低于甲状腺实质、局部不增强、边缘不规则增强或无边缘结构,两者差异具有统计学意义(P<0.05)。结论超声造影显示甲状腺良恶性结节的相对增强时间、内部和边缘增强特征不同。Objective To summarize the enhancement features of thyroid nodules on real time contrast-enhanced ultrasound （CEUS） . Methods Real time CEUS was performed on 102 patients with 117 solid thyroid nodules which were confirmed by pathology, the enhancement and perfusion features were analyzed and compared. Results In early phase of enhancement, most benign nodules were enhanced earlier than or similar to the adjacent thyroid tissue, while most malignant ones were enhanced later. In the peak phase of enhancement, most benign nodules showed hotistic and homogeneous enhancement, higher enhancement intensity and marginal enhancement, while most malignant ones showed non-homogeneous enhancement or non-enhanced areas, lower enhancement intensity and irregular marginal enhancement or vague edge. The difference had statistical significance （P〈0.05） . Conclusions There were statistical difference between benign and malignant nodules in relative enhanced time, intranodular and marginal enhancement features.
