Intraoperative Gamma Probe
One important reflection of the advancing technology is that it can be used to monitor the lymphatic flow of cancer tissue and to detect the presence of millimetric, sometimes cell-based metastases in some tumors that cannot be detected by examination and imaging. The first lymph node (sentinel / guard lymph node) in which the tumor is drained is followed by radioactive labeling and then removed during the surgery with a gamma probe. The intraoperative gamma probe is also used to follow non-palpable breast lesions and minimally invasive parathyroid surgery or radioactivity injection to locate unattached parathyroid adenomas during surgery.
