4D ultrasounds are able to show the baby with complete accuracy and real-time, we see that all gestational ages ago. Here are the big difference with 3D ultrasounds, which only produce an image, typically used in ginecopatologia much and especially to see the morphology of the uterus;if we apply only the baby would see a picture without motion. 4D echo besides being in real time ( 24 frames per second ) can be represented in a sepia color, with what we can clearly see the face, hands, feet and even entire bone structure in volume.
True 4D echo is only useful for parents remain amazed to see his baby, undiagnosed complications, just in case we would say that they look better, especially those concerning the face and limbs, so that the today in obstetrics and rare exceptions, only used for parents to see their hij @ in volume and actual movement, staying very quiet watching his kicks, flickering or yawning. The best time for a 4D Ultrasound is located between weeks 26 and 32, with the 27,28 and 29 weeks, the ideals ( connect www.ecografia4d.es videos to see detail).
To diagnose possible complications, the traditional 2D is the best method. Ideally, make an eco 4D by an expert in prenatal diagnosis and then make an eco 2D valuing the baby all together, seeing him if any Late malformation not observed at 20 weeks, calculating the weight and assessing whether this too“fat” or&ldquo,&rdquo thin ;, if the placenta is working well and the amniotic fluid was adequate amount or as are all flows with Doppler umbilical arteries, brain, uterine etc. When the patient is out of a 4D echo has not only seen his baby in volume and real-time but also will calm because an expert in prenatal diagnosis has performed a complete scan of your baby. Beware of where you see only the face and then not tell you the state of the baby, they are cheaper but do not get a medical report and you know that what you pay.
Often people will often ask if ultrasounds can harm the baby. And the answer is that it is a simple, safe technique and painless. It is, therefore, a safe practice for both the pregnant woman and for the baby, because the latter does not receive the theoretical heat produced by ultrasound. These probes ecografos last generation are studied for microwave not produce any effect on the fetus.
The frequency of realization of ultrasounds can be variable, from a weekly, to a quarterly. In 80 % of cases the routine performance of a 2D ultrasound by trimester is sufficient, there is no reason to perform more, except those couples who wish to make a 4D echo between weeks 26 to 32, in these cases the social security does not cover it, so it MUST sufragarlo privately.
vaginally, the favorite method
The ultrasounds can be performed by via vaginal or abdominal. The vagina is the favorite method of most sonographers in the first weeks of gestation and to measure the cervix in cases where the shortening is suspected, as may occur in the threat of preterm birth, as it provides a sharper image via the abdominal. In the rest of the abdominal ultrasound examinations will be via which we use routinely.
