Clinical application of fine-needle aspiration cytology of thyroid under ultrasonography

Objective:To study the clinical value of fine-needle aspiration cytology in thyroid disease under the guidance of ultrasonography.Meth ods:One hundred and forty-three cases of abnormal thyroid tissue and nodules were aspirated under ultrasonography,then cytological diagnosis was performed.Results:There were four types of cytological diagnosis:①Eighteen cases did not have sufficient cells for diagnosing.②One hundred and thirteen cases were benign.③Nine cases were suspected to have malignancy.④Three cases were malignant .Conclu sion:Thyroid ultrasonography with fine-needle aspiration cytology is a most reliable method for diagnosis of thyroid diseases,especially in distinguishing the benign and malignant nodules.
