Ultrasound pregnancy
What does it consist of?
During the examination, the specialist moves the transducer over the abdomen, having previously applied the gel. This transducer sends sound waves (ultrasound) that “bounce” off different organs and tissues, forming the image.
- Ultrasound 12-14 weeks (first trimester): it is essential to detect the risk of chromosomopathies and review the general condition of the fetus, it also provides information on the characteristics of its vital organs. You will find out if it is a single or multiple gestation pregnancy, you will be able to listen to the rhythm of the heartbeat and see the size of the fetus. During the ultrasound, the risk of pathologies of chromosomal origin, such as Down syndrome, among others, is studied through certain parameters.
- Ultrasound 16-20 weeks (second trimester): it is essential to know the sex of the baby and rule out malformations. In addition, it evaluates the presence of alterations in the umbilical cord, amniotic fluid and placenta. During this ultrasound, if you wish, you will find out the sex of the future baby.
- Ultrasound 26-30 weeks (third trimester): The state and degree of maturation of the placenta, the amount of amniotic fluid and the state of the umbilical cord are studied. Also, the baby’s weight, size and position of the baby inside the uterus are estimated.
