Interventions/Control_1
After obtaining consent for singleton pregnancy after 20 weeks of gestation, when a drug that may affect the hemodynamics is newly administered, a uteroplacental MRI will be taken immediately before drug administration.
Uterine placenta MRI is performed on the same subject as the first imaging after administration of the drug within 7 days after the first imaging.
