Researchers at Washington University School of Medicine in St. Louis have identified areas in the brains of children with Tourette's syndrome that appear markedly different from the same areas in brains of children who don't have the disorder. Above, in a scan of a child with Tourette's, yellow indicates an area with less white matter than in the same brain region in kids who don't have the disorder. The scans also revealed areas in the brains of kids with Tourette's that have more gray matter than in children without the condition. Credit: Washington University School of Medicine

MRI scans of patients with radiation necrosis (above) and cancer recurrence (below) are shown in the left column. Close-ups in the center column show the regions are indistinguishable on routine scans. Radiomic descriptors unearth subtle differences showing radiation necrosis, in the upper right panel, has less heterogeneity, shown in blue, compared to cancer recurrence, in the lower right, which has a much higher degree of heterogeneity, shown in red.
