Diagnostic medical sonogramUltrasound can be used to evaluate the fetal brain of infants from newborn to approximately six months of age, or until there is closure of the anterior fontanelle.

Ultrasound can identify various abnormalities of the infant brain including intracranial hemorrhage, ventriculomegaly, congenital brain anomalies, calcifications associated with intrauterine infections such as Cytomegalovirus (CMV), Syphilis, and Zika.

Neurosonography is the preferred imaging modality of choice for infants.  High resolution brain images can be obtained with sonography thereby eliminating radiation exposure associated with CT scan.  Neonatal head sonography can be performed at the bedside, eliminating the need of bringing a critically ill infant to the Radiology department.  Additionally sedation of the infant is not required to obtain diagnostic ultrasound images.
