Fig. 5. In vivo light scattering spectroscopic differentiation of bile duct malignancy in 29 subjects.

Fig. 5

The color of the bars represents the clinical diagnosis. Light green subjects with benign bile duct, dark green—benign with inflammation, blue—low-grade dysplasia, and red—high-grade dysplasia or cancer. The bar heights represent the light scattering spectroscopy based diagnostic parameter. The red line at 0.2 represents the high-grade dysplasia and cancer diagnostic cutoff established earlier in pancreatic cysts33.
