green (ICG) has shown promising results. In this pilot study, ICG NIR fluorescence imaging was performed to quantify changes in foot perfusion following revascularization.Methods: ICG NIR fluorescence imaging was performed pre-and postrevascularization. After intravenous bolus injection of 0.1 mg/kg ICG, the camera registered the fluorescence intensity over time on the dorsum of both feet for 15 minutes using the Quest Spectrum Platform. Time-intensity curves were plotted for 3 regions of interest (ROIs): (1) the dorsum of the foot; (2) the forefoot; and (3) the hallux. The time-intensity curves were normalized for maximum fluorescence intensity. Derived parameters were the maximum slope, the area under the curve (AUC) for the
