2. Figure
Fluid attenuation inversion recovery images of neurofibromatosis type 1 (NF1) children with (A) and without (B) T2-weighted hyperintensities and of a control (C). Single voxel magnetic resonance spectroscopy of the left capsulolenticular region in NF1 patients (A, B) shows increased choline/creatine and myoinositol/creatine ratios as compared with the control (C); such metabolic abnormalities found both in normal-appearing and in non-normal-appearing brain parenchyma allowed differentiating NF1 patients from controls. The NF1 patient in part A (with T2-weighted hyperintensities) demonstrates slightly higher myoinositol/creatine ratio than the individual in part B (without T2-weighted hyperintensities), which allowed metabolic distinction between patients with and without T2-weighted hyperintensities. N-acetyl aspartate/creatine ratios in both NF1 patients are preserved (i.e., similar to the control), indicating functional neuronal stability in the region.
