Adiposity in small for gestational age preterm infants assessed at term equivalent age.
OBJECTIVE Infants classified as small for gestational age are considered to have developed under adverse intrauterine conditions that lead to lack of fat mass accretion. The aim of this study was to test the null hypothesis that the fat mass in preterm small for gestational age infants assessed at term equivalent age was not different from that of full-term small for gestational age newborns. ...
متن کاملReliability and Repeatability of Quantitative Tractography Methods for Mapping Structural White Matter Connectivity in Preterm and Term Infants at Term-Equivalent Age
Premature infants exhibit widespread insults and delays in white matter maturation that can be sensitively detected early using diffusion tensor imaging. Diffusion tensor tractography facilitates in vivo visualization of white matter tracts and has the potential to be more sensitive than simpler two-dimensional DTI-based measures. However, the reliability and reproducibility of performing tract...
متن کاملAtlas-Guided Quantification of White Matter Signal Abnormalities on Term-Equivalent Age MRI in Very Preterm Infants: Findings Predict Language and Cognitive Development at Two Years of Age
The developmental significance of the frequently encountered white matter signal abnormality (WMSA) findings on MRI around term-equivalent age (TEA) in very preterm infants, remains in question. The use of conventional qualitative analysis methods is subjective, lacks sufficient reliability for producing accurate and reproducible WMSA diagnosis, and possibly contributes to suboptimal neurodevel...
متن کاملProbabilistic diffusion tractography of the optic radiations and visual function in preterm infants at term equivalent age.
Children born prematurely have a high incidence of visual disorders which cannot always be explained by focal retinal or brain lesions. The aim of this study was to test the hypothesis that visual function in preterm infants is related to the microstructural development of white matter in the optic radiations. We used diffusion tensor imaging (DTI) with probabilistic diffusion tractography to d...
متن کاملDiffusion tensor brain imaging findings at term-equivalent age may predict neurologic abnormalities in low birth weight preterm infants.
BACKGROUND AND PURPOSE Low birth weight preterm infants are at high risk of brain injury, particularly injury to the white matter. Diffusion tensor imaging is thought to be more sensitive than conventional MR imaging for detecting subtle white matter abnormalities. The objective of this study was to examine whether diffusion tensor imaging could detect abnormalities that may be associated with ...
