For this reason, all infants weighing less than 1500 grams (about 3⅓ pounds) have a series of ultrasounds. Even if your baby weighs more than this, ultrasounds may be recommended due to prematurity and other factors. …show more content…
• 28–30 days after birth: second head ultrasound.
• 40–45 days after birth: third head ultrasound. This may only be necessary for babies born at 26 weeks or earlier.
There are four types of intracranial hemorrhage that may affect the baby. These are:
• Periventricular-intraventricular hemorrhage (PVH-IVH). This is bleeding in between and around the ventricles. In the intensive care nursery, PVH-IVH is the most common of the four types of
