New guidelines for neonatal neuroimaging, published by the American Academy of Neurology and the Child Neurology Society in the June 26 issue of Neurology, recommend that infants born at less than 30 weeks’ gestation receive screening cranial ultrasound between days 7 and 14.
“Neuroimaging of the developing brain has become an important tool for diagnosing, decision-making, and evaluating treatment effectiveness,” lead author Laura R. Ment, MD, from Yale University School of Medicine, New Haven, Connecticut, says in a news release. “Survival rates have steadily increased among babies born early or with low birth weight. Unfortunately, the incidence of cerebral palsy has not declined in 10 years, and the population of infants at risk is growing.”
According to the guidelines, all preterm neonates born at less than 30 weeks’ gestation should receive screening cranial ultrasonography at age 7 to 14 days and again at 36 to 40 weeks postmenstrual age. Detection of intraventricular hemorrhages significantly alters clinical care, and diagnosis of periventricular leukoencephalopathy or low-pressure ventriculomegaly provides useful information concerning outcome.
