Background The sentinel lymph node (SLN) is the first lymph node (LN) in lymphatic drainage of a tumor and therefore the first potentially metastatically altered LN. To determine this, scintigraphy is commonly used. CEUS lymphography (CEUS-SLN) offers an innovative alternative/supplement. Here, contrast agent (CA) is absorbed and transported away through peritumoral lymph vessels. Only small "proof of concept" studies are available for carcinomas in the head and neck area [1] [2].
