Average vessel radius (microns)	67 ± 28	50 ± 22
Water volume fraction (%)	77 ± 7	76 ± 7
Lipid volume fraction (%)	17 ± 11	19 ± 11
Reduced scattering at 800 nm (cm−1)	17 ± 2	17 ± 3
Mie slope	0.5 ± 0.3	1.0 ± 0.5
Mie-to-total scattering fraction (%)	19 ± 10	37 ± 19

^aAccording to a statistical F-test with p<0.05, 95% of the data showed improvement on the fitting when bile is added to the model.
