What is it?

In infants, the skull bones have not yet fused: the fontanelle (the soft spot on top of the head) lets ultrasound waves through. A cranial (transfontanellar) ultrasound can therefore examine the baby's brain, without X-rays or sedation, as long as the fontanelle is open. It is often used in premature babies. A spinal ultrasound examines the infant's spine and spinal cord in the first months of life, for example when a dimple or a skin abnormality is seen at the bottom of the back (sacral dimple). These examinations are painless. The baby stays in the parents' arms or on the table, calmly; a bottle or a feed can help the baby stay settled.

When is it indicated?

Follow-up of premature babies

It looks for bleeding or a brain abnormality that is common in babies born early.

Abnormal head circumference

It examines the brain and the fluid-filled cavities (ventricles).

Sacral dimple or lower back abnormality

Spinal ultrasound checks the position and appearance of the spinal cord.

Neurological assessment of the infant

At the paediatrician's request, it completes the baby's clinical examination.
