Spectroscopic and statistical analysis on a patient exhibiting hyperplastic nodules, dysplastic lesions and hepatocellular carcinoma. Spectra were acquired using SR-FTIR on frozen tissue sections from the patient #37 and principal component analysis (PCA) was performed on the frequency domains a 3000–2840 cm−1, c 1760–1480 cm−1, e 1480–1360 cm−1, g 1360–1180 cm−1 and i 1180–950 cm−1. The average spectra corresponding to cirrhotic, dysplastic (DN) and tumor nodules (HCC) were extracted and superimposed (b, d, f, h, j)
