(a) Comparison of four AFLS-derived mean-lifetimes, τm, at all four emission wavelengths across three tissue types (PCa, nPZ, and BPH). (b) Comparison of five LRS-derived features across the three tissue types. μs' was calculated at 750 nm, and β-car is scaled down by a factor of 10 for display purposes. For both (a) and (b), the symbol of ‘*’ above bars indicates a statistically significant difference (p < 0.05) when compared to PCa. Error bars are based on standard error of mean.
