FIG 2. Images of an 8-year-old male patient with X-linked adrenoleukodystrophy.

A, Axial view first echo fast-FLAIR image (6000/58 [TR/first TE_eff]; inversion time, 2000 ms).

B, Axial view second echo fast-FLAIR image (6000/160 [TR/second TE_eff]; inversion time, 2000 ms).

C, Corresponding T2 maps of the brain, obtained at the level of the lateral ventricles, show symmetrical and confluent abnormal signal intensity in the deep white matter of the both parietooccipital lobes. Note that regions of highest signal intensity on the T2 map (ie, highest T2 values) correspond to the central zone of low signal intensity on the first echo FLAIR image.
