Note.—CRT signifies cranial radiation therapy; Chemo, chemotherapy regimen; WM, white matter grade determined by MR imaging (4-point scale [see Methods]); VI, ventricular index (maximum width of the frontal horns divided by the maximum internal skull diameter); FA ▵ (%), percentage of reduction in the supratentorial white matter fractional anisotropy of patients versus controls.
