Figure 5

Score plot of PC1 and PC2 from principal component analysis of the spectral region 4.7 - 0.5 ppm from spin-echo MAS MR spectra of irradiated and untreated HT29 xenografts with color coding according to untreated (red)/irradiated (yellow) (A) and amount of necrosis in the samples (B). The corresponding loading profile of PC1 (C). Each point in (A) and (B) represents a single tumor tissue sample.
