A simulation study showing the potential benefit of a radial-trajectory based data acquisition technique named as "radial segmented echo-planar readout (radialSEPI)" for faster fetal angiography is presented. The results indicate that at echo train length of 2 and echo-spacing of 6.1 ms can provide good quality fetal/adult MRA reconstructions providing a potential factor 2 improvement in time.
