What this Trial Is About
Researchers are studying obstetrical pelvimetry, which measures the pelvis to assess complications during labor. The study aims to evaluate new MRI sequences that provide clear images of bone and soft tissues with a shorter scan time. This approach could replace traditional CT pelvimetry, avoiding radiation exposure. The study is led by Cliniques universitaires Saint-Luc and Université Catholique de Louvain and focuses on pregnant women needing pelvic measurements before delivery. Participants will undergo MRI pelvimetry using special sequences that create "pseudo CT" images with high contrast between bone and soft tissue, taking less than 10 minutes. The MRI method is compared to the standard CT pelvimetry to test if it is equally reliable (non-inferior). The study includes women between 33 and 41 weeks pregnant who have plans for pelvimetry outside emergency situations. No masking or blinding is used in this interventional study. During the study, participants will have both MRI and CT pelvimetry examinations, lasting about 30 minutes each, including measurement time. Researchers will assess the reliability of MRI compared to CT and evaluate patient convenience immediately after both exams. The study monitors safety and adherence to the protocol, with informed consent required. Participation spans the imaging procedures and immediate follow-up assessments related to the pelvimetry measurements.
