?:definition
  • Gamma radiation detection probes designed to detect the level of radiation in the superficial area of the neck and/or head 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 imaging or non-imaging gamma radiation devices that display the count rate corresponding to each tissue. Neck/head gamma radiation probes are intended to detect high-radiation points (hot spots), facilitating to find the lymph node to which the tumor drains (sentinel node, SN), helping in the diagnosis and prognosis of cancer tumors and also in the intra-operatively detection of oral, head, thyroid gland, and/or neck carcinomas during procedures.
