Examination and Imaging of the Anterior Fontanelle

Imaging Techniques

• Ultrasonography through the fontanelle provides an excellent window to examine the infant brain without radiation exposure, as recommended by the American Academy of Neurosurgery 1
• Ultrasound examination is often sufficient for anomalies of the cranial sutures and anterior fontanelle before considering more advanced imaging, according to the European Society of Radiology 2
• Transfontanellar ultrasound can be used to evaluate newborns or young infants with open fontanelles for various intracranial conditions, as suggested by the American Heart Association 3
