This clinical trial is focused on patients with breast cancer, melanoma, or head & neck cancer. The study will use a special imaging technique called contrast-enhanced ultrasound (CEUS) to help detect sentinel nodes, which are the first lymph nodes to which cancer cells are likely to spread from a primary tumor. The treatment involves an injection of a contrast agent known as Sonazoid, which contains the active substance perflubutane. This contrast agent helps to improve the visibility of the lymph nodes during the ultrasound procedure.
The purpose of the study is to evaluate how well CEUS can identify sentinel nodes during surgery compared to the current standard method. Participants will undergo a procedure where the Sonazoid contrast agent is injected, and the sentinel nodes are then located using the CEUS technique with the help of a device called the BK5000 US device. This study aims to determine the accuracy of CEUS in finding these nodes and to see if it can predict whether the nodes are cancerous.
Throughout the study, researchers will monitor the time it takes to locate the sentinel nodes using CEUS and assess the ease of using the CEUS system. The study will provide valuable information on whether this method can be a reliable alternative to existing techniques for detecting sentinel nodes in patients with these types of cancer.
