Trial ID: NCT01314963


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.
