Development of a non-invasive, dual-sensor handheld imager for intraoperative preservation of parathyroid glands

Intraoperative localization and preservation of parathyroid glands (PTGs) are challenging during thyroid surgery. Using a technique of combined near-infrared PTG autofluorescence detection and dye-free imaging angiography, this study developed a portable device for localization of PTGs and assessment of viability by confirming tissue perfusion. The imager’s performance was evaluated through a pilot clinical study (N=10).
