Figure 4

Principal component images and plots that demonstrate the first (A), second (B) and third (C) principal components overlaid on the T1CE MR image (right), along with the plot of the corresponding principal eigenvector (left), are shown to illustrate the breadth of information contained within the perfusion time-series. The plots have been constructed from the perfusion signal of all voxels, with the error bar representing +/− two standard deviations of the respective principal component. Red and blue lines represent the negative and positive parts of PCs respectively. The bottom panel shows FLAIR (D), T1 (E), and T1 post contrast images (F).
