【 摘 要 】

The placenta is an organ for transmitting nutrition and oxygen to thefetus; it means if there is a defect in the placenta could make growth restriction to the fetus, even death. Uterine artery flow escalated since the halfway point of the pregnancy or the complete trophoblast invasion of spiralis artery, and keep going in every week. 3D power Doppler examination on placenta could show the uterineplacenta circulation and fetoplacental at once so could give themore accurate result. A cross-sectional study in RSUP HAM and theprivate specialist clinic was conducted in 100 pregnant samples with 28-40 week gestational age, exact last menstrual period date, and no underlying disease to examine the alteration of placental perfusion by gestationalage and placental location. There was a correlation between VI and VFI in placenta toward umbilical artery flow, but no correlation in FI. The placental location also plays a role in interval blood flow, especially FI and VFI, it means the VFI hold the strongest correlation in both ways.
