Near-infrared fluorescence (NIRF) imaging after an intravenous injection of indocyanine green
(ICG) allows for the intraoperative identification of liver anatomy. The investigators have
new data that a much lower dose improves this visualization. Confirmation of this hypothesis
would mean that ICG can be administered on the same day of surgery in order to augment
real-time intraoperative visualization, thereby providing a safe, feasible, and
cost-effective strategy for the surgical treatment of liver disease.
