Atlas-based MRI analysis is one of many analytical methods and is used to investigate typical as well as abnormal neurodevelopment. It has been widely applied to the adult and pediatric populations. Successful applications of atlas-based analysis (ABA) in those cohorts have motivated the creation of a neonatal atlas and parcellation map (PM). The purpose of this review is to discuss the various neonatal diffusion tensor imaging (DTI) atlases that are available for use in ABA, examine how such…

Construction of Neonatal Diffusion Atlases via Spatio-Angular Consistency
TLDR
This paper proposes to construct the atlas by jointly considering diffusion-weighted images of neighboring gradient directions by employing a group regularization framework where local patches of angularly neighboring images are constrained for consistent spatio-angular atlas reconstruction.
Spatio‐angular consistent construction of neonatal diffusion MRI atlases
TLDR
This article proposes a patch‐based method for diffusion‐weighted (DW) atlas construction that employs a group regularization framework where local patches of angularly neighboring images are constrained for consistent spatio‐angular atlas reconstruction.
A Multi‐Atlas Label Fusion Tool for Neonatal Brain MRI Parcellation and Quantification
TLDR
A T1‐weighted, neonatal, multi‐atlas repository is developed and integrated into the MALF‐based brain segmentation tools in the cloud‐based platform, MRICloud.org, which will make the latest MALf tools readily available to users, with minimum barriers, and will expedite and accelerate advancements in developmental neuroscience research, neonatology, and pediatric neuroradiology.

Robust Construction of Diffusion MRI Atlases with Correction for Inter-Subject Fiber Dispersion.
TLDR
This paper proposes a method to improve the construction of diffusion atlases in light of inter-subject fiber dispersion that involves a novel q-space (i.e., wavevector space) patch matching mechanism that is incorporated in a mean shift algorithm to seek the most probable signal at each point in q- space.
Diffusion Tensor Imaging
TLDR
A comprehensive understanding of the acquisition and visualisation methods and their limitations in the context of brain anatomy is essential to fully realise the potential of DTI.
Robust Fusion of Diffusion MRI Data for Template Construction
TLDR
This paper proposes a method to improve the construction of diffusion MRI templates in light of inter-subject differences that involves a novel q-space (i.e., wavevector space) patch matching mechanism incorporated in a mean shift algorithm to seek the most probable signal at each point in q- space.
Post-hemorrhagic ventricular dilatation affects white matter maturation in extremely preterm infants
TLDR
Extremely preterm infants with post-hemorrhagic ventricular dilatation showed lower fractional anisotropy values in their corpus callosum compared with controls reflecting the impaired microstructure of these commissural nerve fibers that are adjacent to the dilated ventricles.
Sex-Specific Alterations of White Matter Developmental Trajectories in Infants With Prenatal Exposure to Methamphetamine and Tobacco.
TLDR
Prenatal methamphetamine/tobacco exposure may lead to delays in motor development, with less coherent fibers and less myelination in SCR and PCR only in male infants, but these abnormalities may normalize by ages 3 to 4 months after cessation of stimulant exposure.

TLDR
The regressional results indicate that this is an effect of intensity changes due not solely to myelination processes but also likely brain dehydration processes in early postnatal development.
