The C-Trak® Galaxy System sets a new standard in intraoperative gamma probes. A gamma probe is an instrument used to detect radiation in patients. It functions a bit like a small and highly directional Geiger counter, and is designed principally for use in surgery. Surgeons often find it difficult to locate tissues, such as tumors, parathyroid glands, and lymph nodes, within the human body. Proper use of a gamma probe allows the surgeon to make a smaller incision and have greater confidence that exploration was successful, and the tissues of interest have been located.
One of the most common uses of gamma probes is in a surgical procedure called a Sentinel Node Biopsy. Sentinel Node Biopsies can be used to determine whether a tumour has metastasized, or spread to new locations. Sentinel Node Biopsies are common for staging breast cancer and melanoma, and are becoming increasingly popular in staging other forms of cancer. Sentinel Node Biopsies most commonly use a radioisotope called Technetium-99m.
C-Trak® OmniProbe® PET devices can also be used to detect very high-energy radioisotopes such as Flourine-18, which is commonly delivered in a solution called FDG. FDG can be used to find a wide variety of types of cancer, and has a promising outlook for future development.
