Legend Axial T2 (left) and proton density-weighted (right) images demonstrate abnormal high signal involving the left posterior frontal and parietal lobes. The area of signal abnormality is well demarcated and involves gray and white matter.

Legend Restricted diffusion is seen (left) confirmed by low signal on the ADC map (middle). T1 axial (top right) and sagittal (bottom right) reveal a gyriform pattern of high signal in the same regions.

Legend Proton MR spectroscopy (short TE): Voxel 2 is normal. Voxel 1 demonstrates elevated lactate and lipid. The relatively high choline/creatine ratios and low NAA in both voxels are normal in the newborn. Key words: mri dwi mrs stroke ischemia vascular pediatric newborn
