Fig. 3.

The representative cases of low- (upper) and high- (lower) grade gliomas, including the 16-class DTcIs that showed the highest classification performance. The T1-weighted images, DTcIs, seven diffusion tensor images and the ratios in each class number are shown for each patient. DWI = diffusion-weighted imaging; FA = fractional anisotropy; L1 = first eigenvalue; L2 = second eigenvalue; L3 = third eigenvalue; MD = mean diffusivity; S0 = raw T2 signal without diffusion weighting. Each colour on DTcIs and circular charts correspond to each class number, shown in the colour bar.
