Diagnostic Accuracy of Longitudinal Evaluation of Central Nervous System Sonoelastography in Preterm and Term Neonates

The objective of this study was to evaluate the brain elasticity of the central nervous system in preterm and term neonates. Methods Seventy-seven healthy preterm and term neonates (mean gestational age [GA], 37.5 weeks; range, 32.6–40.5 weeks) were included in the study. Periventricular and subcortical white matter, cortical gray matter, and ventricle and subdural spaces were examined with strain elastography ratios. Each patient underwent sonography evaluation twice. The mean age at the time of sonographic evaluation was 9 days (range, 4–15 days) for the first evaluation and 37 days (range, 31–47 days) for the second evaluation. The ratios were correlated with GA, birth weight. Results The caudate nucleus and cortical gray matter strain ratios were significantly higher than the periventricular and subcortical white matter strain ratios (P
