Abstract

OBJECTIVE:

Several studies have shown a relation between the size of corpus callosum (CC) and outcome in preterm infants. Three-dimensional ultrasound (3D-US) offers new perspectives in cerebral imaging. To establish reference values for biometry of the CC in very low birth weight infants and to correlate these measurements to neurodevelopmental outcome at 5 years of age.

STUDY DESIGN:

Forty-three preterm infants with a gestational age >32 weeks were included. Transfontanellar 3D-US measurements were obtained at nine different timepoints.

RESULTS:

3D-US-based reference values for size, length, circumference and surface area of the CC could be established. Measurements at term-equivalent age showed a correlation to neurodevelopment outcome.

CONCLUSION:

Reliable biometric data of the CC can be established in preterm infants by 3D-US and correlate with neurodevelopmental outcome.
