DTI results images (FA, CM, AD, RD, MD) from a normal human subject. A T1-weighted image (T1wMRI) that depicts the traditional MRI view of brain anatomy has been aligned and resliced to match the DTI images. These images illustrate that DTI provides directional information about white matter fiber array orientation that is not present in traditional T1-weighted MRI and that DTI provides quantitative images of water diffusivity parallel to an perpendicular to the fiber array orientation. The color system used for the CM is displayed to the lower right of the CM. The CM allows the reader to immediately visualize the directional orientation of the primary eigenvector in the left-right, anterior-posterior, superior-inferior co-ordinate system.
