Characterization of Fetal Lung With Quantitative Ultrasound

NCT06722365 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 16

Last updated 2026-02-13

No results posted yet for this study

Summary

The purpose of the study is to show if it's possible to use a special kind of ultrasound called backscatter quantitative ultrasound (bQUS) to check on a baby's lungs when the mother is 36 weeks pregnant. 16 participants will be on study for a single 30 minute ultrasound between 32 and 36 weeks of pregnancy.

Conditions

  • Respiratory Complication
  • Fetal Lung Imaging

Interventions

DEVICE

Backscatter Quantitative Ultrasound

The intervention consists of a regular abdominal ultrasound scan for fetal evaluation. The difference with a regular scan is that the scanner used to image the fetus provides access to raw/unprocessed ultrasound echo data that can be extracted from the scanner and processed offline (after acquisition) to extract compute backscatter quantitative ultrasound (bQUS) features. Thus, data acquisition does not represent a significant departure from conventional fetal imaging protocols. Other than the time needed to acquire the images, the participant will not perceive any difference from a regular fetal ultrasound scan.
