Table 1 Statistical analysis on seven patients who received intravenous ICG during the TRUSPA imaging.Slopes for change in the mean signal of the entire prostatic region between pre- and post-ICG injection for the measurements 800 nm (peak absorption of ICG), 950 nm (very low absorption of ICG), and unmixed ICG. Total of *n* = 70 measurements adjusted for dose and clustering within patient were used in the analysis. The fourth column “is slope = 0?” provides the probability for no change in signal difference between respective pre- and post-measures, and the fifth column “is slope = ICG slope?” provides the probability that the slope of a certain measurement (800 or 950 nm) follows the ICG slope.
