Brain region segmentations. A color-coded 3D rendering of a patient's brain with an axial MRI slice transecting it at the level of the image shown on the right. The axial slice on the right demonstrates the regions of interest (ROIs) that were segmented at each level on the scan to generate the 3D structures for comparison. The ROIs consisted of structures that were large (whole brain without ventricles, ventricles, and cerebellum) and small (lentiform nucleus, thalamus, corpus callosum, and caudate).
