Early diagnosis of FGR is vitally important for the management of pregnancy and delivery planned accordingly. IVIM MRI is a non-invasive, in vivo techniques which can assess placental perfusion quantitatively, and be useful for evaluating placental microcirculation. In this study, the IVIM parameters of placental was measured and to investigate whether FGR pregnancies have different placental perfusion compared with normal pergnancies. The results show that perfusion fraction (f) have a significantly lower in FGR group. And f value moderately incresased with increasing gestational age in normal pregnancies.
