Four patients missed the second set of measurements. The power Doppler mode was not applied at any time during the visit to investigate the pregnancy itself (the fetus or the trophoblastic tissue). Therefore, data concerning the fetus, gestational sac, or placenta do not include any power Doppler information.
**Vascularization, volume multiplied with VI. Values are mean ± SEM or n (%). 17-OHP = 17 hydroxyprogesterone
