Prediction of Fetal Growth Restriction Using Placental Image Features in BOLD MRI Open
Fetal growth restriction (FGR) is a disease during pregnancy that increases the risk of preterm birth and perinatal death. Currently, the diagnosis of FGR relies on ultrasonography-based estimated fetal body weight (EFBW). However, EFBW ca…

Two-dimensional phase-contrast MRI reveals changes in uterine arterial blood flow in pregnant women administered tadalafil for fetal growth restriction Open
UtA blood flow in pregnant women with FGR was significantly lower than that in healthy pregnant women. Tadalafil is expected to improve UtA blood flow, thereby improving placental function in pregnant patients with FGR.
