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.
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.
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.
