Efficacy of Gamma Camera Used Intraoperatively for ID of Sentinel Lymph Nodes w/ Lymphoscintigraphy

This study evaluates the ability of a prototype intraoperative handheld gamma camera (pIHGC) to image (detect) sentinel lymph nodes (SLNs) in melanoma and breast cancer during surgical excision, as compared to standard of care intraoperative gamma probes (GP). The unit of study in this trial was SNLs rather individual participants. Each device was assessed for relative node detection sensitivity (S) of those SLNs.

Stanford is currently not accepting patients for this trial.
