Probes, Gamma Radiation Detection, Lymphatic Mapping

Definition : Gamma radiation detection probes designed to detect the level of radiation in lymphatic nodes around a cancer tumor after prior ingestion or injection of a radiopharmaceutical tracer (i.e., radioactive drug). These probes typically consist of a detector, a collimator, and shielding from radiation outside the intended target; they are used with non-imaging gamma radiation devices that display the count rate corresponding to each node. Lymphatic mapping gamma radiation probes are used to detect high-radiation points (hot spots), facilitating to find the lymph node to which the tumor drains (sentinel node, SN), helping the pathologist to identify lymph node metastasis status.

Entry Terms : "Lymphatic Mapping Gamma Probes" , "Sentinel Node Mapping (SND) Gamma Probes" , "Hot Node Mapping Gamma Probes"
