摘要

•Placental malperfusion is associated with placental dysfunction.•Placental perfusion fraction (f) can be assessed by DWI MRI in vivo.•f is reduced in placentas with histological evidence of fetal vascular malperfusion.•Given a large intra-placental variation in f, the clinical relevance of the method may be limited.
