What this trial studies

This observational study aims to assess the effectiveness of two advanced ultrasound technologies, quantitative ultrasound (QUS) and ultrafast power Doppler imaging (uPDI), in evaluating placental health and blood flow in singleton pregnancies. The primary objective is to differentiate between healthy pregnancies and those affected by fetal growth restriction (FGR). Secondary objectives include monitoring changes in ultrasound imaging over the course of pregnancy and identifying potential complications related to placental insufficiency. The study will utilize both experimental and FDA-approved ultrasound machines to gather data.

Who should consider this trial

Good fit: Ideal candidates are pregnant individuals aged 18 to 45 with singleton gestations between 18 to 26 weeks, who are at low risk for fetal growth restriction.

Not a fit: Patients with known risk factors for fetal growth restriction or those with multiple gestations may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection of placental issues, potentially reducing risks associated with fetal growth restriction.

How similar studies have performed: While the use of ultrasound techniques for placental assessment is established, the specific combination of QUS and uPDI in this context is novel and has not been extensively tested.
