Diffuse reflectance spectroscopy accurately quantifies various degrees of liver steatosis in murine models of fatty liver disease

Table 1 Accuracy calculations of DRS analysis with respect to macrovesicular steatosis in the CD-AA and CS-AA diet groups

	Result pathology positive for macrovesicular steatosis	Result pathology negative for macrovesicular steatosis
Positive result DRS analyses	57	14	71
Negative result DRS analyses	0	13	13
	57	27	84
Sensitivity	100 %
Specificity	48 %
Positive predictive value	80 %
Negative predictive value	100 %

The DRS analyses are positive for steatosis when the determined fat fraction value is larger than 5 %
