Evaluation of Neonatal Brain Parenchyma Using 2-Dimensional Shear Wave Elastography
1Department of Radiology, Gaziosmanpasa University, Medical Faculty, Tokat, Turkey.
Summary
Neonatal brain stiffness differs between preterm and term infants. Two-dimensional shear wave elastography can detect these differences, offering reference points for evaluating brain stiffness in neonates.
Area of Science:
- Neuroimaging
- Biophysics
- Neonatal Medicine
Background:
- Neonatal brain development is complex and can be affected by prematurity.
- Assessing brain tissue properties non-invasively is crucial for understanding neonatal neurological conditions.
Purpose of the Study:
- To evaluate neonatal brain stiffness using 2D shear wave elastography (SWE).
- To compare brain stiffness between term and preterm neonates.
- To identify potential differences in stiffness between brain regions.
Main Methods:
- 83 neonates (44 term, 39 preterm) underwent 2D SWE via the anterior fontanel.
- Measurements were taken from the thalamus and occipital periventricular white matter.
- Correlation and ROC analyses were used to assess stiffness and predict prematurity.
Main Results:
- Preterm neonates showed significantly lower brain stiffness in both thalamus and white matter compared to term neonates.
- Periventricular white matter was consistently less stiff than the thalamus in both groups.
- Specific stiffness cutoffs were identified for predicting prematurity.
Conclusions:
- 2D SWE can effectively differentiate brain stiffness between term and preterm neonates.
- Findings provide reference values for neonatal brain stiffness.
- This technique may aid in research for various neonatal neurological conditions.
