Trial Outcomes & Findings for PED NEONAT 20-000599 Fetal Body Composition (NCT NCT04508751)

Last Updated: 2023-08-30

Results Overview

MRI data will be reconstructed by Siemens scanner software to produce 3D fat-water separated images and PDFF maps. The FB-MRI radial data will be transferred to a separate workstation for custom reconstruction of 3D fat-water-separated images and PDFF maps and analysis. Visceral adipose tissue PDFF values will be directly measured from regions of interest.

Participant milestones

Participant milestones
Measure	Healthy Pregnancy Patient will have a fetal MRI performed in the third trimester. All MRI scans will be performed on 3 T scanners (e.g., Skyra or Prisma, Siemens). Our newly developed FB-MRI quantification technique leverages a multi-echo 3D stack-of-radial sampling trajectory with golden-angle acquisition ordering to suppress motion artifacts and enable free-breathing imaging of the abdomen in around 5 minutes. In addition, our FB-MRI technique is compatible with data under sampling to accelerate the free-breathing scan to 1-2 min. In this study, we will optimize the parameters of our FB-MRI technique (spatial resolution, spatial coverage, acceleration factor) to balance trade-offs between scan time, image quality, fat quantification accuracy, and patient comfort/compliance. Subjects will be provided ear plugs to limit amount of noise from MRI machines. Maternal demographics, pregnancy clinical course and infant growth parameters will be recorded. 3T "Free-Breathing" Fetal Magnetic Resonance Imaging: Subject will have a one time MRI scan.	Pregnant Mothers With Gestational Diabetes Patient will have a fetal MRI performed in the third trimester. All MRI scans will be performed on 3 T scanners (e.g., Skyra or Prisma, Siemens).
