“…In contrast to what had previously been shown using MRI VV and 2-D US images by Horsch et al, 7 we did not find strong correlations between VV and linear measurements. This could partially be due to a higher variance in volume measurement made on 3-D US in comparison with MR images as the boundaries are less clear in US images.…”

Abstract. The aim of this study is to compare longitudinal two-dimensional (2-D) and three-dimensional (3-D) ultrasound (US) estimates of ventricle size in preterm neonates with posthemorrhagic ventricular dilatation (PHVD) using quantitative measurements of the lateral ventricles. Cranial 2-D US and 3-D US images were acquired from neonatal patients with diagnosed PHVD within 10 min of each other one to two times per week and analyzed offline. Ventricle index, anterior horn width, third ventricle width, and thalamo-occipital distance were measured on the 2-D images and ventricle volume (VV) was measured from 3-D US images. Changes in the measurements between successive image sets were also recorded. No strong correlations were found between VV and 2-D US measurements (R 2 between 0.69 and 0.36). Additionally, weak correlations were found between changes in 2-D US measurements and 3-D US VV (R 2 between 0.13 and 0.02). A trend was found between increasing 2-D US measurements and 3-D US-based VV, but this was not the case when comparing changes between 3-D US VV and 2-D US measurements. If 3-D US-based VV provides a more accurate estimate of ventricle size than 2-D US measurements, moderate-weak correlations with 3-D US suggest that monitoring preterm patients with PHVD using 2-D US measurements alone might not accurately represent whether the ventricles are progressively dilating. A volumetric measure (3-D US or MRI) could be used instead to more accurately represent changes. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.

“…Indeed, only a few studies directly comparing 2-D US and MRI measurements of the ventricles have been done. 7,8 Specifically, Horsch et al 7 found that the AHW was strongly correlated with MRI VV (R 2 ¼ 0.88) when preterm born infants with varying ventricle sizes were imaged at term equivalent age.…”

“…Although cranial ultrasound is the diagnostic imaging of choice for ruling out the appearance of brain pathology in the population of high-risk preterm neonates (93)(94)(95)(96), and clearly an acoustically quieter examination than an MRI, some consider MRI to be more accurate. Linear measurements from cranial ultrasound have been strongly correlated with major neonatal cerebral sites seen on MRI (72,93,(97)(98)(99), although several regions, including the posterior horn depth of the lateral ventricle and the cortex of the cingulate gyrus, may appear to be slightly narrower than when measured sonographically (97). For that reason, in the present study we intentionally chose not to focus on absolute values of brain measurements, but rather report normalized values based on the TTD of each infant.…”

Brain development is largely shaped by early sensory experience. However, it is currently unknown whether, how early, and to what extent the newborn's brain is shaped by exposure to maternal sounds when the brain is most sensitive to early life programming. The present study examined this question in 40 infants born extremely prematurely (between 25-and 32-wk gestation) in the first month of life. Newborns were randomized to receive auditory enrichment in the form of audio recordings of maternal sounds (including their mother's voice and heartbeat) or routine exposure to hospital environmental noise. The groups were otherwise medically and demographically comparable. Cranial ultrasonography measurements were obtained at 30 ± 3 d of life. Results show that newborns exposed to maternal sounds had a significantly larger auditory cortex (AC) bilaterally compared with control newborns receiving standard care. The magnitude of the right and left AC thickness was significantly correlated with gestational age but not with the duration of sound exposure. Measurements of head circumference and the widths of the frontal horn (FH) and the corpus callosum (CC) were not significantly different between the two groups. This study provides evidence for experience-dependent plasticity in the primary AC before the brain has reached full-term maturation. Our results demonstrate that despite the immaturity of the auditory pathways, the AC is more adaptive to maternal sounds than environmental noise. Further studies are needed to better understand the neural processes underlying this early brain plasticity and its functional implications for future hearing and language development. auditory | brain | mother's voice | heartbeat | preterm newborns
