Imaging abnormalities evident on T1, T2, diffusion and Susceptibility Weighted Images in congenital heart disease neonates (N = 19). * = obtained post operatively; R = right; L = left; CC = corpus callosum; WM = white matter; IVH = intraventricular hemorrhage; ↓, = decreased; ↑ = increased; NC = no change. Note subjects 14, 16 and 18 were imaged post operatively and the remaining 16 preoperatively.
