Using MRI for safer pelvic measurements in pregnant women

Official title: MRI Pseudo-CT Sequences for Obstetrical Pelvimetry

Run by Cliniques universitaires Saint-Luc- Université Catholique de Louvain · NCT06485323 · Data updated 2026-11-12

This study is testing a new MRI method to safely measure the pelvis in pregnant women without using radiation, to see if it works as well as traditional CT scans.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are pregnant women between 33 to 41 weeks who have previously had a cesarean section and require pelvimetry for their next pregnancy.

Probably not a fit

Patients with contraindications to MRI, such as pacemakers or severe claustrophobia, will not benefit from this study.

What this trial studies

This study evaluates the use of advanced MRI sequences to perform pelvimetry, which is a measurement of the pelvis, as a non-irradiating alternative to traditional CT pelvimetry. The focus is on new MRI techniques that provide optimal contrast between bone and soft tissue while significantly reducing acquisition time to under 10 minutes. The goal is to validate this rapid MRI approach to ensure it is as reliable as CT for assessing pelvic dimensions in pregnant women. This could lead to safer imaging practices for expectant mothers.

Why it matters

Potential benefit: If successful, this approach could eliminate radiation exposure for pregnant women while providing accurate pelvic measurements.

How similar studies have gone: Preliminary tests have shown promise for similar MRI techniques, but this specific approach is novel and requires validation.
