What is it?
Obstetric ultrasonography uses sound waves to create a visual representation of the developing embryo or fetus in its mother’s uterus.
Ultrasonography uses ultrasound and not X-rays.
An ultrasound emitting probe is applied to your stomach. The wave propagates in the tissue and is reflected by the fetus in the form of an echo. This signal is analyzed by a powerful computer system that transforms this information into a live image.
The ultrasound machine has four main elements:
• The probe that emits ultrasound and receives the signal after passage through the tissue. It is connected to the camera.
• The video screen.
• The computer…
• The control panel.
During your pregnancy, three ultrasounds are performed and they occur ate the first, second and third quarter. Other scans may be made if necessary.
Obstetric Ultrasound studies the development of the fetus, the placenta and the cord to:
• Monitor the pregnancy;
• Detect a possible defect.
• Screen morphological abnormalities (each organ is studied one at a time);
• Allows to date the exact start of pregnancy;
• Determine the number of fetuses;
• Look for malformations
• Measure the size of the head, femur, abdomen;
• Assess fetal development;
• Appreciate the mobility of the fetus thus its vitality.
