Principal components based on higher variance of GBM and normal areas: (black curve) variance magnitude of 17 normal areas from T1-WI, T2-WI, and FLAIR, (blue curve) variance magnitude of 17 GBMs chosen from T1-WI, (red curve) variance magnitude of 17 GBMs chosen from T2-WI, and (green curve) variance magnitude of 17 chosen GBMs chosen from FLAIR mode of MRI.
