甲状腺癌是临床常见病,由于其具有隐匿性,大多数患者无明显临床症状,早期仅表现为甲状腺结节,因此,甲状腺结节的良恶性鉴别是其诊断要点。超声造影是近年来发展起来的一种新型超声技术,是对传统超声手段的补充,在甲状腺结节的鉴别诊断方面有重要价值。本文综述近年有关甲状腺超声造影在鉴别良恶性结节的研究进展,旨在为超声造影的临床应用提供参考。 Thyroid cancer is a common clinical disease, because of its occult, most patients without obvious clinical symptoms, the early performance of thyroid nodules, therefore, benign and malignant thyroid nodules is the diagnosis of its main points. Ultrasonography is a new type of ultrasound developed in recent years. It is a supplement to traditional ultrasound and has important value in the differential diagnosis of thyroid nodules. This review summarizes the research progress of thyroid ultrasound in the identification of benign and malignant nodules in recent years, and aims to provide a reference for the clinical application of contrast-enhanced ultrasound.
