Ultrasonographic examination was performed in 70 healthy neonates and infants using
a real-time sector scanner array machine with a 7.5-MHz transducer and a 4 cm waterbag.
The skin, subcutaneous tissue, dura mater, interhemispheric fissure, gyri, sulci and
sagittal sinus could be clearly visualized on ultrasonography (US), and the distance
from the dura mater to the brain surface was determined. The extracerebral space under
the anterior fontanel increased until 3 months after birth, and decreased gradually
from 3 months to 12 months.
The width and structure of the extracerebral space seen on US can be useful as parameters
for assessing the process of brain growth and for detecting extra- and intracerebral
pathologies in neonates and infants.
