Regional segmentation of MRM scans. Images in A, B, and C are representative coronal, sagittal, and horizontal scans, respectively. Illustrated are color-coded regions that were manually segmented for each of the brains examined for this study. Computer-generated 3-D reconstruction of these regions provides a basis for volume determinations and for visualization of normal and abnormal morphology. Illustrated in (D) is a brain reconstruction with the upper portion of the right side removed, allowing visualization of interior structures.
