Proper placental function is essential for normal fetal development. MRI can easily assess the growth and development of the placenta throughout gestation due to its capabilities in functional imaging. However, uterine contractions, and fetal and maternal motion can lead to inaccuracies in the quantitative assessments. In this we assessed the impact of extraneous motion on placental imaging by using a 3D multi-echo golden angle radial sequence to generated dynamic images of the placenta.
