WebAll the oncological patients underwent MRI scans after RT. The increase in white matter hyper-intensities on the T2-weighted images, markedly on the periventricular regions, was consistently evident from 30–45 to 45–65 Gy and were localized mainly in the internal capsule, the paraventricular frontal and basal ganglia areas. WebCRH-ir neurons are also present in the glomerular layer of the olfactory bulb, in the periventricular layer of the optic tectum, and caudal to the glomerular nucleus.
