Could MRI replace CT for safer pelvic measurements in pregnancy?
NCT ID NCT06485323
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether MRI can be used instead of CT to measure the pelvis in pregnant women who have had a previous C-section. CT scans use radiation, which doctors want to avoid. The study will enroll 95 women and compare the accuracy of the two methods, as well as how comfortable each exam is for the patient.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could make pelvic measurements safer for pregnant women by replacing CT scans with radiation-free MRI.
- What could go wrong
- This is a small, early-stage study (95 people) comparing two imaging methods. MRI may not be as accurate as CT, and results may not apply to all pregnancies.
