Injecting indocyanine green (ICG) at a constant rate clarifies fluorescence. The green box indicates the constant rate group, and the fluorescence intensity in the circulation area is 184.2 (154.2-227.5), which is higher than that of the bolus group (120.3 [68.0-194.0]) (purple box) (P = .0003). There is no difference in the fluorescence intensity in the ischemic area between the 2 groups. Even in the reference image of the constant rate, a clear boundary line is obtained without increasing the amount of ICG, and the effectiveness in identifying the segmental line is confirmed.
