NCI: A procedure that uses radioactive substances to locate tumors so that they can be removed by surgery.,NCI: Radioguided surgery is an innovative means by which a radionuclide is used to preoperatively image and intraoperatively visualize a structure of interest to the surgeon for excisional biopsy. This technology has allowed a cost-effective, highly specific means by which to locate a structure (usually a lymph node) and access it for pathologic analysis. The result of radioguided surgery is increased specificity in tissue obtained for biopsy, minimal access incisions, and the reduction of inpatient hospital utilization. (from Medscape)
