Head and neck ultrasound is a diagnostic imaging technique that uses ultrasound waves to examine organs and parts inside the neck. The neck is surrounded by important organs such as the larynx, thyroid gland, salivary glands, cervical lymph nodes, tonsils, etc., so head and neck ultrasound helps detect many abnormalities in this area.

Carotid ultrasound of the neck is a widely used method to detect early atherosclerotic plaques that cause carotid artery stenosis and aneurysms. This method helps predict the risk of stroke effectively.
