简要总结
Ultrasound measurements of fetus during first trimester may be an indicator of first trimester pregnancy loss. Investigators took 4 measurements of the fetus on 2 intervals during first trimester to confirm this hypothesis.
详细描述
Ultrasound examination of gestational sac (GS) diameter, yolk sac (YS) diameter, crown rump length (CRL) diameter, embryonal heart rate (HR) using Samsung Medison SonoAce R3 through transvaginal probes (6.5 MHz) was conducted on 126 pregnant women. At least 2 scans were done for each participant one between 6-8 weeks and another one by the end of first trimester. Results then were compared to get the cut off values that can predict pregnancy loss.
