Supraclavicular Lymph Nodes – Radiology In Plain English
3 days ago · Supraclavicular lymph nodes are located just above the collarbone (or clavicle). These lymph nodes filter lymphatic fluid, helping to identify and fight foreign pathogens. When they swell or become tender, it can indicate an underlying infection or cancer. Imaging tests play an important role in assessing supraclavicular lymph nodes.
