title: [Sonographic evaluation of metastatic cervical lymph nodes].
abstract: Cervical nodal metastases are common in patients with head and neck cancers. Early assessment is important for treatment planning and prognosis. Ultrasound has been widely used in the evaluation of neck lymph nodes, with common parameters including location, size, shape, boundary, hilus, echogenicity, vascular pattern, and resistance index. The diagnostic accuracy has been dramatically improved along with the introduction of new techniques including contrast-enhanced ultrasound, elastography, and ultrasound-guided fine needle aspiration biopsy. Neck ultrasound has became an important tool in preoperative assessment and postoperative follow-up for patients with head and neck cancers.
