FIG 5. 12-year-old boy hit by a car. Patient had a poor outcome (GOS score = 4, severe disabilities) at 12-month follow-up. Total mean metabolite ratios from MRSI were 1.14 (decreased) for NAA/Cr, 1.13 for NAA/Cho, and 1.11 (increased) Cho/Cr.
A and B, Contiguous SWI images show a moderately large hemorrhagic lesion in the deep right frontal lobe.
C, Corresponding T2-weighted MR image shows the lesion (circle) with an overlay of the volume of interest (rectangle). Boxes indicate corresponding voxels in D.
D, Spectral map shows loss of metabolite signal intensity in area of the lesion (circle) and (2) a spectrum from normal-appearing left FWM with markedly decreased NAA/Cr and increased Cho/Cr, as compared with (3) a spectrum from normal-appearing parietal white matter with decreased NAA/Cr and normal Cho/Cr.
