What is the primary purpose of using ultrasound in neck examinations?

The primary purpose of using ultrasound in neck examinations is to visualize soft tissue structures. Ultrasound is a non-invasive imaging technique that provides real-time images of the body's internal structures. In the context of the neck, it is particularly effective for assessing lymph nodes, thyroid glands, salivary glands, and other soft tissues. This imaging modality is valuable because it can help detect abnormalities such as cysts, tumors, or infections without the need for more invasive techniques like biopsies or surgical explorations.

Ultrasound uses high-frequency sound waves to create images, allowing clinicians to differentiate between various tissue types based on their acoustic properties. This technique is essential in clinical practice for diagnosing conditions that involve soft tissue pathology in the neck region.
