Principal Component Scores of raw and preprocessed FTIR images of mouse liver exposed to acetaminophen. The rows represent control, 0.5 h, 3 h and 6 h images respectively. The first three columns represent PC1, PC2, PC3 score images of the raw FTIR spectra. The last three columns represent PC1, PC2, PC3 score images of the preprocessed FTIR spectra. Dark blue regions in the preprocessed images (4th, 5th and 6th columns) indicate the presence of glass substrate. Uniformity within the same image and differentiation capability across different time points is enhanced by preprocessing the data
