[Head circumference in relation to sonographic morphometry of the cerebral ventricles in neonates and infants].

AIM

To determine normal values of sonographic measurements of the brain in neonates and infants.

METHOD

Cerebral ultrasonographic examinations were performed in 143 healthy newborns and infants. The size of the ventricles was determined by ascertaining distances as well as performing planimetric measurements of the ventricular area and circumference in standardized planes.

RESULTS

Throughout the course of the study we observed a continous increase in size and a strong correlation with head circumference. The middle coronary plane used for the measurements allows the accurate representation of the ventricles and a more objective assessment of size.

CONCLUSION

Based on the morphometric data, charts for the determination of ventricular size were developed.
