Design outcomes

Primary

Measure	Time frame
The assessment of the reproducibility of measuring the placental perfusion in women with singleton pregnancies between 14- and 16-weeks*gestational age	—

Secondary

Measure	Time frame
1. To assess whether it is possible to repeatedly measure the blood velocity and diameter of the uterine arteries and veins, and umbilical arteries and vein. 2. What are the differences in measurements between the two umbilical arteries? 3. Does a relation between the uterine artery and vein flow exist? 4. Does a relation between the umbilical arteries and vein flow exist? 5. The assessment of intra-observer variability.	—
