Thousands of cases of fetal growth restriction occur annually that can lead to complications at birth. In order to get a better idea of condition and to develop better monitoring technology, the National Institutes of Health has granted $3.2 million to researchers at Baylor College of Medicine and Texas Children's Hospital.

The researchers are tasked with developing "an improved way to evaluate umbilical venous blood flow using 3D and Doppler ultrasound techniques" in small fetuses, according to a release from Baylor College of Medicine.

"Our research team will initially validate the accuracy and reproducibility of new 3D volume flow measurements and then develop corresponding reference ranges in normal pregnancies," says Dr. Wesley Lee, professor of obstetrics and gynecology at Baylor, in the release.

"Detailed observations of fetal growth, heart function, and circulatory changes will be made in over 1,000 small fetuses with estimated weights below the 10th percentile," Lee continues. "The results will be correlated with pregnancy outcomes to identify prenatal predictors of clinical problems in newborns."

The grant will fund a five-year investigation collaboration between the two Houston hospitals, as well as the University of Michigan, Perinatology Research Branch of the Eunice Kennedy Shriver National Institute of Child Health, and Human Development and GE Healthcare.

FGR is a condition that affects fetuses that are below the weight normal for their gesticular age — usually in the 10th percentile of weight or less, according to Stanford Children's Health. Underlying issues with placenta or umbilical cord can increase the risks of the condition and causes of FGR can range from blood pressure problems to drug and alcohol use.

Affected fetuses can be at risk of stillbirth or neonatal death. Babies that overcome FGR complications at birth are predisposed to developmental delay and the development of adult diseases such as obesity, diabetes, coronary artery disease, and stroke, according to the release.

According to Dr. Lee, identifying these FGR and at-risk fetuses can benefit their health in infancy as well as throughout their lives.
