Fetal Blood Flow Measurements at Low Field (0.55T) using Metric Optimized Gating
Motivation: To allow diagnosis of CHD at low field strengths in order to increase the accessibility of MRI.Goal(s): To demonstrate that acquiring 2D phase contrast sequences in utero at 0.55T is possible. Approach: Acquire 2D Phase contrast sequences, optimize sequences parameters, and perform metric optimized gating and flow measurementsResults: Umbilical vein, descending aorta, and superior vena cava flow in utero measurements were calculated. Impact: Fetal flow measurements provide additional information on the complex hemodynamics in complex CHD cases – potentially enhancing antenatal counselling and postnatal surgery planning. Optimizing these for emerging low field MRI scanners widens their availability.
