Cranial ultrasound is a technique for scanning the brain using high-frequency sound waves. It is used almost exclusively in babies because their fontanelle (the soft spot on the skull) provides an "acoustic window". A different form of ultrasound-based brain scanning, transcranial Doppler, can be used in any age group.
An ultrasound showing an embryo measured to have a crown-rump length of 1.67 cm and estimated to have a gestational age of 8 weeks and 1 day. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump).
Acrania is a rare congenital disorder that occurs in the human fetus in which the flat bones in the cranial vault are either completely or partially absent. [1] The cerebral hemispheres develop completely but abnormally. [1] The condition is frequently, though not always, associated with anencephaly. The fetus is said to have acrania if it ...
Cranial ultrasound is usually only used in babies, whose open fontanelles provide acoustic windows allowing ultrasound imaging of the brain. Advantages include the absence of ionising radiation and the possibility of bedside scanning, but the lack of soft-tissue detail means MRI is preferred for some conditions.
[1] [3] In the United States, to perform the test was known as "Dubowitzing the baby". [1] [4] Lilly and Victor Dubowitz returned to London's Hammersmith Hospital in 1972, where Lilly pioneered the use of cranial ultrasound and, later, magnetic resonance imaging to assess the brains of newborns.

John’s Hopkins noted that cranial helmets are “used to gently correct the shape of babies’ skulls over time. Newborn babies’ skulls are soft plates with spaces between them. As the baby ...
