Placental Volume, Flow, and Vascularity Study
United States440 participantsStarted 2021-03-10
Plain-language summary
The purpose of this preliminary study is to implement an automated and standardized computer-based method that accurately measures placental volume, blood flow, and vascularity. This will be accomplished by using the digital data obtained at the time of a first-trimester 3D image volume. This information will then be used to further investigate whether placental volume, blood flow, and vascularity can be used to predict the risk of preeclampsia in conjunction with maternal history and serum blood markers obtained at the time of their ultrasound.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Singleton gestation
* Qualify for a first-trimester screen at the time of enrollment. Criteria for the screen include pregnancy with gestational age between 10 weeks 3 days and 13 weeks 6 days of gestation as well as a crown-rump length between 40 and 84 mm.
* Complete a first-trimester ultrasound at the qualifying M Health Fairview Maternal Fetal Medicine Clinics, which include University Riverside, Ridges, South Dale, and Health East sites
* Provide a blood sample for either completion of the first-trimester screen and/or for the completion of the research study
Exclusion Criteria:
* Multi-fetal gestation or pregnancy with major fetal congenital anomalies and/or known fetal aneuploidy
* Unwilling to complete a first-trimester ultrasound and/or unwilling to provide a serum sample
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
