NCT02840019

Brief Summary

The goal of Advanced Fetal Imaging - Phase II is to advance fetal MRI imaging by designing MRI coils specifically for pregnant women and testing recently developed MRI image acquisition techniques. The investigators aim to more reliably obtain higher quality fetal MRI images when compared to current clinical fetal MRI.

Outcome Measures

Primary Outcomes (1)

  • Research fetal MRI image quality compared to standard clinical fetal MRI image quality

    Research fetal MRI image quality will be compared to the standard clinical fetal MRI image quality.

    July 2016-December 2019, up to 41 months

Secondary Outcomes (2)

  • Research fetal MRI image quality compared to standard obstetric ultrasound image quality

    July 2016-December 2019, up to 41 months

  • Research MRI physiological data compared against standard obstetric physiological data obtained from ultrasound

    July 2016-December 2019, up to 41 months

Study Arms (2)

60 minute research full MRI scan

EXPERIMENTAL

Pregnant women who are able to have an MRI are eligible for the 60 minute research full MRI scan. Pregnant women may have a healthy pregnancy, a concern for fetal/placental abnormalities with a clinical fetal MRI ordered by their doctor, or a concern for fetal/placental abnormalities without a clinical fetal MRI ordered by their doctor. The investigational MRI coil designed for pregnant women and research MRI sequences will be tested during the 60 minute research scan.

Device: Investigational MRI coil designed for pregnant womenProcedure: MRI Scan

15 minute research add-on MRI scan

EXPERIMENTAL

Pregnant women with a concern for fetal/placental abnormalities with a clinical fetal MRI at Boston Children's Hospital are eligible for the 15 minute research add-on MRI scan. The research MRI sequences will also be tested during the add-on research MRI scan.

Procedure: MRI Scan

Interventions

MRI ScanPROCEDURE

All participants will participate in an MRI scan. The add-on MRI scan will be 15 minutes. The full MRI scan will be 60 minutes.

15 minute research add-on MRI scan60 minute research full MRI scan

The investigational MRI receiver coil designed specifically for pregnant women will be used during the 60 minute full research MRI scan. An MRI receiver coil is part of the MRI machine that is placed over the body part being imaged during every MRI scan. A coil is required to obtain MR images, yet there isn't one designed for pregnant women. This investigational MRI receiver coil for pregnant women will be tested to see if it helps improve image quality and take images faster.
