简要总结
The researchers' objective is to use diffusion-tensor imaging (DTI) to evaluate infants diagnosed with cerebral white matter injury during the neonatal period and identify antenatal risk factors, electronic fetal heart rate monitoring abnormalities, and umbilical arterial gas results that are associated with cerebral white matter injury. The researchers' hypothesis is that this new imaging technique will help us better understand how these devastating injuries occur.
详细描述
Maternal and neonatal data will be collected as well as the umbilical arterial gas results and the electronic fetal heart rate tracing of the labor. Infants will have a head ultrasound at 24-72 hours, 10-14 days, and at 4-6 weeks to look for cerebral white matter injury, as standard of care. All infants with a birth weight < 1500 grams will be offered DTI, and infants > 1500 grams with white matter injury diagnosed by ultrasound will be imaged as well as the subsequent delivery born within 7 days of that gestational age without brain injury. All infants will have the DTI brain scan at 12-18 months of age corrected for the degree of prematurity, and will also have a formal neurological assessment at that time.
