However, fluorescence guidance remains limited by its superficial nature. This study evaluated the feasibility of a nuclear medicine–based navigation concept that allowed intraoperative positioning of a fluorescence camera (FC) in the vicinity of preoperatively defined ICG-99mTc-nanocolloid containing sentinel nodes (SNs). Methods: Five patients with penile cancer scheduled for SN biopsy were injected with ICG-99mTc-nanocolloid followed by preoperative SPECT/CT imaging. The navigation device was used to provide a real-time augmented reality overlay of the SPECT/CT images and video output of the FC. This overlay was then used for FC navigation. Results: SPECT/CT identified 13 SNs in 9 groins. FC navigation was successful for all 12 intraoperatively evaluated SNs (average error, 8.8 mm; range, 0–20 mm). Conclusion: This study reveals the potential benefits of FC navigation during open surgery procedures.
