This test uses sound waves to produce a picture of your neck and lymph nodes on a computer screen. Lymph nodes are part of the lymphatic system, which helps to protect us from infection and disease.The scan is painless and only takes a few minutes. The doctor puts some gel onto your neck and moves a small device which produces sound waves over the area. They look for any changes in the size or appearance of the lymph nodes in your neck.We have more information about ultrasound scans.
