How much time is enough? Sentinel lymph node mapping time depends on the radiotracer agent

Background In 2014, technetium‐99m tilmanocept (TcTM) replaced technetium‐99m sulfur colloid (TcSC) as the standard lymphoscintigraphy (LS) mapping agent in melanoma patients undergoing sentinel lymph node biopsy (SLNB). The aim of this study was to examine differences in mapping time, intra‐operative identification of sentinel lymph node (SLN), and false negative rate (FNR) between patients who underwent SLNB with TcTM compared to TcSC.
