The infant brain undergoes drastic morphological and functional development during the first year of life.

Three-dimensional T1-weighted Magnetic Resonance Imaging (3D T1w-MRI) is a major tool to characterize the brain anatomy, which however, manifests inherently low and rapidly changing contrast between white matter (WM) and gray matter (GM) in the infant brains (0-12 month-old).

Despite the prior efforts made to maximize tissue contrast in the neonatal brains (≤1 months), optimization of imaging methods in the rest of the infancy (1–12 months) is not fully addressed, while brains in the latter period exhibit even more challenging contrast.

Here, we performed a systematic investigation to improve the contrast between cortical GM and subcortical WM throughout the infancy.

We first performed simultaneous T1 and proton density mapping in a normally developing infant cohort at 3T (n = 57).
