FIG 1. Images of a 13-year-old male patient with X-linked adrenoleukodystrophy.

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

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

C, Axial first echo conventional spin-echo MR image (3000/30 [TR/first TE]).

D, Axial second echo conventional spin-echo MR images (3000/100 [TR/second TE]) 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 and splenium of the corpus callosum. The peripheral (arrowheads) and central (asterisks) zones are most distinct on the first echo fast-FLAIR image.
