Percentage volume differences across irradiated and control mice at the P98 time point after cranial irradiation at a juvenile age. Images under the “Anatomy” header represent coronal slices of a consensus average brain image. The image panels from left to right and top to bottom represent consecutive coronal slices, proceeding from caudal to rostral slices. The position of the slices can be seen in the sagittal brain legend (top right). Images under the “P98” header represent the same set of slices, with a color scale superimposed to represent radiation-induced volume changes. The color scale shows percentage volume difference by structure across irradiated and control mice. Results demonstrate widespread volume losses.
