Intraoperative Near-Infrared Autofluorescence and Indocyanine Green Imaging to Identify Parathyroid Glands: A Comparison

Figure 2

Parathyroid gland exposed to normal white light (a) and near-infrared light 2 min after i.v. application of 5 mg ICG (b). The gland displays a strong fluorescence indicating a good vascularity. The surrounding structures, especially the thyroid, are less fluorescent.
