“…In addition, one study achieved the measurement of brain volume in preterm infants using 2D-CUS (estimated absolute brain volume, EABV), and multiple regression analysis showed that ventricular enlargement, postnatal resuscitation, bronchopulmonary dysplasia, and late-onset sepsis could be independent risk factors leading to reduced brain volume. Follow-up results of Psychomotor Development Index (PDI) showed a mild positive correlation with EABV, that is, preterm infants with lower EABV had a worse PDI, indicating that abnormal changes in brain volume in preterm infants can affect the long-term neurodevelopmental outcomes of preterm infants [ 33 ].…”

“…A better approach to the evaluation of brain growth pattern during admission in the NICU could help in the identification of this dysmaturation process. While some researchers have proposed different linear measurements as a proxy of early measurement of brain volume ( 12 , 13 ), these studies have not compared the estimated TBV with manual segmentation in 3D US or MRI estimated TBV, which could be considered the gold standard. Moreover, longitudinal estimation of brain volume though US has not been systematically tested as most of the studies rely on MRI for volumetric assessment of brain structures.…”

Objectives: The aim of this study is to explore if manually segmented total brain volume (TBV) from 3D ultrasonography (US) is comparable to TBV estimated by magnetic resonance imaging (MRI). We then wanted to test 2D based TBV estimation obtained through three linear axes which would enable monitoring brain growth in the preterm infant during admission.Methods: We included very low birth weight preterm infants admitted to our neonatal intensive care unit (NICU) with normal neuroimaging findings. We measured biparietal diameter, anteroposterior axis, vertical axis from US and MRI and TBV from both MRI and 3D US. We calculated intra- and interobserver agreement within and between techniques using the intraclass correlation coefficient and Bland-Altman methodology. We then developed a multilevel prediction model of TBV based on linear measurements from both US and MRI, compared them and explored how they changed with increasing age. The multilevel prediction model for TBV from linear measures was tested for internal and external validity and we developed a reference table for ease of prediction of TBV.Results: We used measurements obtained from 426 US and 93 MRI scans from 118 patients. We found good intra- and interobserver agreement for all the measurements. US measurements were reliable when compared to MRI, including TBV which achieved excellent agreement with that of MRI [ICC of 0.98 (95% CI 0.96–0.99)]. TBV estimated through 2D measurements of biparietal diameter, anteroposterior axis, and vertical axis was comparable among both techniques. We estimated the population 95% confidence interval for the mean values of biparietal diameter, anteroposterior axis, vertical axis, and total brain volume by post-menstrual age. A TBV prediction table based on the three axes is proposed to enable easy implementation of TBV estimation in routine 2D US during admission in the NICU.Conclusions: US measurements of biparietal diameter, vertical axis, and anteroposterior axis are reliable. TBV segmented through 3D US is comparable to MRI estimated TBV. 2D US accurate estimation of TBV is possible through biparietal diameter, vertical, and anteroposterior axes.
