Ultrasonography (USG) will probably be one of the most enjoyable examination during pregnancy. You and your partner can see the growing baby in the womb. The examination is also a useful tool to get detailed information on the development of the fetus. Ultrasound examination did not pose a danger to you or the baby. The possibility of adverse effects has been widely studied and proven to have never found a problem.
Ultrasonography is the examination results of two-dimensional images of the fetus or embryo developing in the mother’s pregnant belly. The examination includes the use of high frequency sound waves that are created by installing transformers on a device called the transducer.
Transducer will receive and transmit sound waves. Transducer moves above the gel that is applied to the maternal abdomen. The transducer collects sound waves echo when it bounces on the baby, then the computer will translate it into an image. The situation can be illustrated as radar used by aircraft or submarine terrain to create a picture in the dark of night or in the bottom of the ocean.
Before the examination, you may be asked to drink 1 liter of water. By drinking water, health technicians will make it easier to see the uterus. The bladder is located in front of the uterus. If the bladder is full, then the uterus pushed forward and out of the pelvic area and can be seen easily through ultrasound. If the bladder is empty, the uterus will be located further down in the pelvis and will make it difficult to see.
Ultrasound examination can also help confirm the dates of birth of your baby, whether the baby or a twin, and determine the major physical characteristics of the fetus under normal circumstances. Ultrasound examination can be performed at any time during pregnancy.
Did you have to undergo an ultrasound or not depends on several factors such as bleeding problems, previous pregnancy problems, and insurance. Generally, doctors perform an ultrasound examination at least once during pregnancy. If your pregnancy is high risk, then you will usually undergo several examinations.
Your doctor may instruct an ultrasound to obtain important information about the brain, spinal cord, face, great organ, limb, or the sex of the fetus. Ultrasound examination can show the location of the placenta so that the information can be used with other tests, such as amniocentesis. The examination can also provide information about the growth of the fetus, umbilical cord conditions, and the amount of amniotic fluid in the womb.
Physician or medical technician will usually do an ultrasound for the following reasons:
To identify early pregnancy.
To show the size and speed of growth of the embryo or fetus.
To measure the fetal head, abdomen, or thighs to determine the duration or length of pregnancy.
To identify a particular fetus with Down syndrome.
To identify fetal abnormalities, such as hydrocephalus.
To identify the location, size, and maturity of the placenta or placental abnormalities.
To detect the IUD.
To differentiate between miscarriage and ectopic pregnancy (pregnancy outside the uterus).
