X x6 Y or 6x8x8 cm VOIs, yielding hundreds of sub 2 cm 3 voxels in under 30 minutes. Six children with NF1, ranging in age from 10 months to 11 years old, have been studied with this technique. This indicates that the disease's metabolic processes have already begun, but have not yet altered her anatomy. Her MRI and MRS were compared with a matched control. Three approximately corresponding slices from an age and sex matched normal control and equal-size NAA maps.
All maps are on the same quantitative scale.
Note near complete elimination of the lipid's signal. The FIDs were either added or subtracted from the average according to f in Table 1. The G X , G Y and G Z gradient pulses are crushers only. Thus, it is a sought indicator of neuronal injury of any source. Its CH 3 group yields a prominent peak in the 1 H-MRS of the brain.
