“…In prospective studies, it was found that, compared with a gamma probe, fhSPECT improved SLN identification rates in melanoma and breast cancer patients [53,57,58]. Detecting gamma emission from different angles increased the sensitivity and enabled the detection of SLNs containing only a small amount of radiotracer, deep-lying nodes, and SLNs overlaid by fatty tissue (e.g., in obese patients) [32,57,58]. Based on these promising results, the technology was transferred to the complex HN area [54,59].…”
