Fig 3.

A 6-day-old male neonate with respiratory depression. Axial MR images illustrate bright myelination of the medial lemnisci (long arrows), lateral lemnisci (dotted arrows), cranial nerve V fascicle (dashed arrows), and SCP (beveled arrows) on GRE-T1WI (A and B), which were not clearly visible on SE-T1WI (not shown), but all appeared dark (myelinated) on SE-T2WI (C and D). The medial lemnisci were visibly myelinated in ≥94% of neonates on both GRE-T1WI and SE-T2WI. In most patients, the lateral lemnisci and cranial nerve V fascicle were best visualized as being myelinated on GRE-T1WI.
