Iron Conjugated Polymers in Saline Suspension

**Semantic type:** Indicator, Reagent, or Diagnostic Aid

**Definition:** A magnetic tracer composed of a suspension containing iron conjugated to polymers that can potentially be used as a contrast agent for detecting sentinel lymph node metastases using magnetic resonance imaging (MRI). Upon intravenous administration of the iron conjugated polymers in saline suspension, the iron conjugated polymers may collect in sentinel lymph nodes and lymph node metastases may be detected upon MRI.

**Synonyms:** - FerroTrace (TM)
