Many mothers like to see their babies so often go for ultrasound during pregnancy. But according to experts, just three times is enough to know if he has a problem, that is on the 12th, 22nd and 32nd weeks.

Sometimes you impatiently wait for an appointment to see your face. Ultrasound is a moment of enchantment, full of interesting surprises, ways to help people who are about to be parents integrate with the fetus. The principle of ultrasound is a device placed on the skin that emits ultrasound waves through the tissue, going deep in to read the signal. After a reception, the signal is analyzed by an informatics system, conveying the image that appears on the screen.

The time of an initial ultrasound scan is the 12th week (or two and a half months pregnant). The goal is to verify whether the embryo is good, having one or two pregnancies in the same one; write the date to calculate before birth. This ultrasound also verifies the health status of the embryo (fetal heart measurement), how the uterus blooms, dilates (to account for difficult births).

The second time is during 4 months and half months of pregnancy or the 22nd week. The doctor will check the baby's development, measure the extremities, the length from the head to the coccyx, the diameter of the skull, abdomen, determine the presence of agencies.

The third ultrasound (week 32 or 7 months) aims to detect some abnormalities in morphology, shape of fetal structure due to the previous ultrasound not seen. From the 2nd and 3rd time, the doctor examined blood circulation in the umbilical cord, intrauterine arteries, especially for mothers with signs of blood disease (diabetes, kidney failure, and blood). pressure); check the position and posture of the fetus; see the volume of amniotic fluid .

Repeated ultrasound is still at risk because radiation always affects tissue layers. There are areas very sensitive to ultrasound, doctors call them soft areas like eyes, gonads. This is the area that is most "prone" when the doctor keeps increasing the wave on the face and genital organs for non-medical purposes, but only to draw the image of the fetus. Experts say that ultrasound is a medical technique, only performed when diagnosis is needed, should not be considered as a photograph to watch and play.

Would 3D ultrasound be better?

Measurement of fetal length, diameter, cut lines to compare with normal sizes . all done via 2-way ultrasound, called 2D, white and black. For some parents, such images are difficult to see. Since the 90s, 3D ultrasound reproduces a better quality image, the fetus appears unexpectedly as an authentic baby, big or small, depending on the time of pregnancy. Since the appearance of 3D ultrasound, people have been very sympathetic to this technique.

According to ultrasound experts, 3D ultrasound is not used for detection. Which size, which cuts to make . are 2D scans. Don't believe that 3D is better than 2D. 3D ultrasound is for additional tests only when conditions are present.
