Identify the myelination landmarks on MRI for a newborn (0 days old). What are the characteristic T1 and T2 signal patterns?

In a newborn, high T1 signal is observed in the dorsal brainstem, ventrolateral thalamus, lentiform nucleus, and central corticospinal tracts. Low T2 signal is noted in the posterior portion of the posterior limb of the internal capsule. Key diagnostic features include recognizing these signal patterns as normal for age, which helps differentiate from pathological conditions. A common pitfall is mistaking these normal high T1 and low T2 signals for lesions; understanding normal myelination patterns is crucial to avoid misdiagnosis.
