ClinConnect Summary

This clinical trial is investigating a new way to check a baby’s lungs using a special ultrasound technique called backscatter quantitative ultrasound (bQUS). The goal is to see if this method can provide valuable information about the lungs when mothers are around 36 weeks pregnant. The study will involve 12 pregnant women who will participate in a single 30-minute ultrasound between 32 and 36 weeks of pregnancy.

To join this study, women must be between 18 and 45 years old, be expecting one baby (not twins or more), have a live fetus, and be scheduled for a routine ultrasound to check the baby’s growth. They should not be in labor and must meet certain health criteria. During the ultrasound, participants can expect to lie comfortably while the technician uses the ultrasound equipment to evaluate the baby’s lungs. This research could help improve how doctors monitor fetal lung health in the future.
