when can ultrasound detect brain issues
Ultrasound waves cannot pass through bones, so an ultrasound to evaluate the brain cannot be done after the bones of the skull (cranium) have grown together. Cranial ultrasound can be done on babies before the bones of the skull have grown together or on adults after the skull has been surgically opened. It may be used to evaluate problems in the brain and ventricles in babies up to about 18 months old.
