Injectable tracer material consisting of a suspension of superparamagnetic particles (approximately 60 nM in diameter) designed to allow mapping of lymphatic pathways when used in combination with a detection system based on magnetic susceptibility. Superparamagnetic particles in these lymphatic mapping tracers are designed to flow through lymphatic ducts but become trapped in lymph nodes. Lymphatic mapping magnetic tracers are typically used in sentinel lymph node biopsy procedures.
