Fetal cardiac MRI methods used in the prenatal diagnosis of coarctation of the aorta.

Key Points

Fetal cardiac MRI predicted postnatal coarctation of the aorta with high accuracy, enhancing diagnostic capability.
Using 4D flow MRI, researchers quantified fetal cardiovascular flow volumes and distribution for better evaluation.
Cardiac gating with a DUS gating device allowed for precise image acquisition of fetal heart structures and vasculature.
Fetal CMR methods may improve prenatal, peri-, and postnatal care of newborns diagnosed with aortic coarctation.

Abstract

Motivation: A clinical need to better diagnose aortic coarctation (CoA) in third trimester using fetal CMR. Goal(s): To describe technical parameters and results of fetal CMR for the prenatal evaluation of suspected CoA. Approach: Cardiac gating was obtained using a DUS gating device. 4D flow MRI was acquired to quantify fetal cardiovascular flow volumes and distribution. Cine balanced SSFP sequences were acquired of the fetal heart and great vessels. Multiplane T2w-BB sequences were acquired, and a 3D dataset was created to demonstrate extracardiac vasculature. Results: Using fetal CMR we were able to predict postnatal diagnosis of CoA with a high degree of accuracy. Impact: Fetal CMRI improved the prenatal diagnosis of CoA which can improve pre-, peri-, and post-natal care.
