FIGURE 8.
White light, speckle contrast and ICG fluorescence images of a well-vascularized left superior parathyroid gland and a partially devascularized left inferior parathyroid gland, taken during a thyroid lobectomy case. The low speckle contrast of the superior gland is supported by strong ICG fluorescence in the gland, and the high speckle contrast of the inferior gland is supported by its minimal ICG fluorescence. Parathyroid glands are indicated by white ellipses.
