After decades of development

ultrasound (US) has become the first-line imaging method in the diagnosis and treatment of thyroid diseases since US was applied in thyroid in 1967. The risk stratification system of thyroid nodules based on conventional US plays a pivotal role in the diagnosis of thyroid diseases. In recent years

contrasted-enhanced US (CEUS)

molecular diagnosis based on thyroid fine-needle aspiration biopsy and artificial intelligence have been widely used in thyroid diseases diagnosis. Thermal ablation of thyroid tumors has played the advantages of precise positioning

less trauma and maximum preservation of thyroid function. The relevant guideline consensuses regulate the minimally invasive treatment operation of thyroid diseases. Thyroid science popularization will further standardize the diagnosis and treatment of diseases and improve the treatment level of nationwide. This review summarized the representative research progress in the field of thyroid US in 2022.
