Abstract

A 59-year-old man with laryngeal cancer was scheduled to receive sentinel lymph node (SLN) navigation surgery. Radioactive colloids were endoscopically injected around the tumor. Three hours after injection, preoperative lymphoscintigraphy was performed using a new portable CdTe semiconductor camera as well as a conventional gamma camera. The semiconductor camera successfully identified an SLN neighboring the primary tumor over an acquisition time of only 30 seconds, whereas the conventional camera could not clearly visualize the SLN over the same acquisition time. This semiconductor camera also imaged the SLN in the operating room, 19 hours after the injection.
