Ultrasound in pregnancy, also called sonogram or ultrasound, is the first eye contact with the baby, and may contribute to an awakening of an even greater emotional bond between the mother and the baby. In addition is a way to verify how the pregnancy is developing.
What Is It and How Does the Ultrasound?
The traditional ultrasound allows to see the baby in a two-dimensional image. The ultrasound is a noninvasive test that uses sound waves, and through the echo of these waves creates an image of the baby, the placenta from the uterus and other organs. It’s a very important exam to obtain necessary information on the progress of the pregnancy and the baby’s health.
During the test, by means of a transducer, are sent to high-frequency sound waves to the abdomen. These waves “hit” on baby making an echo effect, and are sent to the computer, translating an image. The computer translates the sounds that ECHO is received back in video images, which reveal so the format of the baby, your position and movements.
Usually a gel is placed on the abdomen, and then a device called a transducer is passed over this gel, sending money to the abdomen. There is also the intravaginal ultrasound, used in early pregnancy, up to 11 weeks, when the fetus is still too small to be detected otherwise.
Ultrasound waves are also used in the device that the obstetricians use to hear the baby’s heartbeat.
The ultrasounds are done in various stages of pregnancy, for numerous reasons when buying baby jackets and coats. A pregnancy without problems, are usually made between 3 to 4 ultrasounds. However, the height of the scans, and the amount of times you do, will depend on how the pregnancy progresses.
Is usually made between the 6 and 13 weeks of pregnancy. Within this period will come out especially early if there is a history of gestational loss, bleeding or a fertility treatment. Can be used a special probe, which is placed in the vagina, because the common equipment can, more premature at this stage, unable to detect the baby.
Ultrasound for Dating the Baby
This type of ultrasound is done between the 13 and 16 weeks and serves to date the pregnancy. Probably will do a pelvic ultrasound, where the transducer is placed on the skin over the area of the pelvis.

The person conducting the examination, make the comments about what you see, and make images to take baby steps, so this is a good occasion to take home the first picture of your little one.
This examination is done between 10 and 13 weeks, and serves to predict the risk of the child suffering from Down syndrome. This test measures the amount of accumulated fluid in the back of the neck of the baby, that is the thickness of the fold of neck, which, if it is increased, may indicate a possible Down syndrome. The doctor will use the measure made by scan, your age and a blood test to measure the risk of this possibility. If the risk is higher than 1:00 pm 300, you may have to do a biopsy of the villus sampling (the cells are extracted from the placenta with an ultrathin needle) or amniocentesis (the fluid is extracted from the amniotic sac around the baby).
This ultrasound is done to most pregnant women around 19-20 weeks of pregnancy to detect possible abnormalities in the baby. Are measures the circumference of the head and the abdomen of the baby and your heart, brain, spine and limbs. At this point you can also find out the sex of the baby.
After 20 Weeks
You may have to do additional ultrasound if you have any complications, such as placenta previa. If there is a history of genetic defects, such as defects in the heart, you may have to do more scans, or if you have a multiple pregnancy. About 30-34 weeks of pregnancy the obstetrician may ask you for an ultrasound for the determination of the position of the baby, the placenta, amniotic fluid volume and the prediction of the baby’s weight.

There are studies done comparing babies who have been through an ultrasound and others not yet done, and apparently these studies conclude that the ultrasounds are perfectly safe.
What the Future of Ultrasound Technician?
The new ultrasound or ultrasounds allow a 3D image that let me see the baby the 3 dimensions instead of the common 2. The 3D image is formed by a set of two-dimensional images. These images give a clear picture of the shape of the baby. For now, the benefits of ultrasound in 3D (three dimensions) seem to be limited in relation to the common 2D ultrasound. May be useful to show more details about any faults detected already. Also help to diagnose problems such as cleft lip. The 3D ultrasound can also be useful to assess the heart and other internal organs. The best time to do an ultrasound in 3D is between 26 and 30 weeks of pregnancy, because before the baby does not have fat enough to be possible to obtain a good picture.
