Comparing quantitative values of two generations of laser-assisted indocyanine green dye angiography systems: can we predict necrosis?

Abstract

Intraoperative comparison of LAICGA systems has provided direct correlation of perfusion values predictive of necrosis that were previously established in the literature. An APU value of 3.7 from the SPY 2001 correlates to a SPY Elite APU value of 23.8.
