027) were observed in the HUP and NUP group, respectively. An inverse association was observed between UC and progesterone levels. normal contractility) in terms of patient age and the presence of any uterine factor (adenomyosis, myomas, adhesions, or polyps). There were no differences between the groups (hypercontractility vs. Overall, an average of 1.1 cpm was found in the study population. The institutional review board's approval was obtained. SPSS version 21.0 was used for the statistical analysis. The intraclass correlation coefficient was used to validate variability. The highest quartile defined the hypercontractility group (>1.51 cpm n = 41), considering the remaining quartiles as the normal contractility group (≤1.51 cpm n = 156). To define high-frequency UC, we separated uterine peristalsis (contractions per minute ) into quartiles. They were counted on a ×15 accelerated recording video. The contractions were seen like waves going through the endometrial cavity. Uterine contractility (UC) was assessed by recording a 6-minute-long video using a 4D mode (Voluson E10 General Electric, Boston, MA), which was performed by a single operator (B.M.). The participants were evaluated for uterine contractions and serum progesterone levels (10-30 minutes before the embryo transfer procedure). Because it is known that most failures are attributed to the quality of the embryo, we deemed it important to explore the potential uterine factors explaining the failures in oocyte donation cycles, the use of which decreases the probability of embryo-related factors influencing it. The study included 197 consecutive patients undergoing in vitro fertilization (from 2018 to 2019) with a history of recurrent implantation failure (defined as unsuccessful implantation of a total number of ≥3 blastocysts originated from oocyte donation cycles). Instituto Bernabeu of Alicante is a private clinic. The videos were also analyzed by a senior doctor, junior doctor, and a nurse for their reproducibility. Many expecting mothers have written back to us that their babies make the same gestures and put hands and feet in the face after birth just as they did in the womb and it makes them treasure the ultrasound images even more.To study uterine peristalsis using step-by-step 4-dimensional (4D) ultrasound assessment video, explore its relationship with progesterone levels in a select in vitro fertilization population, and assess the reproducibility of the technique.įour-dimensional uterine ultrasound and a retrospective analysis of outcomes in relation with progesterone levels. Similarly, babies are often going to be putting their hands and feet in their face and may not free up a view of the entire face. We will do our best to get as much of the face in view as possible but a full face shot is not always available. Some of the images will have parts of the placenta in them, after all, we are imaging the baby in the womb. In some cases, the baby will face into the placenta, whether it is anterior, posterior (along the back) or fundal (along the top), in which case, we will work to try to get the baby to move away from the placenta. A large percentage of our clients have anterior placenta and we are able to scan from the side and around the placenta to see the baby. Not necessarily, Many clients with anterior placenta ( in front ) often ask if there will be difficulty seeing their baby with a 3d/4d ultrasound.
