title: Thyroid ultrasonography. Part 2: nodules.
abstract: This article reviews common ultrasonographic patterns identified in both benign and malignant thyroid nodules. Categorizing nodules into benign and malignant patterns may be helpful to decide if ultrasound-guided fine-needle aspiration (FNA) should be performed. In addition, the FNA biopsy guidelines issued by major organizations are reviewed.
