Cerebral computed tomography in premature infants, with an attempt at staging developmental features.

Cerebral computed tomography of 45 infants has been carried out for a better assessment of the normal appearance of the different anatomical structures. The skull vault is often asymmetrical, the dura mater is very dense, and the ventricular system is small in contrast with the large subarachnoid spaces. The brain parenchyma contains zones of low attenuation, mainly frontal. These may well be a normal developmental feature.
