Diffusion Tensor Imaging Studies on Recovery of Injured Optic Radiation: A Minireview

Figure 2

Reconstruction of the optic radiation (OR) using a probabilistic algorithm (the Oxford Centre for Functional Magnetic Resonance Imaging of Brain Software Library; http://www.fmrib.ox.ac.uk/fsl). (a) Regions of interest (ROIs): seed ROI, the optic tract posterior to the optic chiasm in the coronal plane; target ROI 1, the lateral geniculate body in the coronal plane; target ROI 2, the bundle of the OR at the posterior one-third portion between the lateral geniculate body and the primary visual cortex. (b) Results of diffusion tensor tractography of the OR. (c) Axial and sagittal slices of probabilistic tractography show reconstruction of the OR with Meyer’s loop (green arrows).
