Radioguided surgery is an innovative means by which a radionuclide is used
to preoperatively image and intraoperatively visualize a structure of inter
est to the surgeon for excisional biopsy. This technology has allowed a cos
t-effective, highly specific means by which to locate a structure (usually
a lymph node) and access it for pathologic analysis, The result of radiogui
ded surgery is increased specificity in tissue obtained for biopsy, minimal
access incisions, and the reduction of inpatient hospital utilization. Rad
ioguided surgery should not be confused with radiosurgery, which is the ste
reotactic application of external beam radiation, usually for intracranial
tumors.
