Fig. 7

Discrimination between various cirrhotic nodules using synchrotron radiation or a laboratory-based infrared source. Spectra were acquired on frozen tissue sections from the patient #37 using SR-FTIR (a, b, e, f) or using a Globar-FTIR microscope (c, d, g, h). Principal component analysis (PCA) was performed on the frequency domain 1180–950 cm−1. The score plot based on PC1 and PC2 is shown where each point represents one spectrum (a, c, e, g) and the average spectra were extracted and superimposed (b, d, f, h).
