Figure 1 (A-D).

(A, B): Axial magnetic resonance imaging (MRI) of a 5 day old full-term neonate at the level of internal capsule. (A) T1 weighted image (WI) shows normally increased signal intensity (SI) of the posterior limb of internal capsule relative to the basal ganglia and thalamus; (B) Corresponding T2WI shows normal hypointense signal of the posterior limb of internal capsule; (C, D): Just above (A, B), shows normal variation in SI of the basal ganglia and thalamus. (C) T1WI shows normally increased SI of the posterior limb of internal capsule (large black arrow) and ventrolateral thalamus (small black arrows). Note the moderate hyperintensity of globus pallidus, which is a normal variation (small white arrow). (D) Corresponding T2WI shows normal hypointense signal of the posterior limb of internal capsule
