Ultrasound (also called sonogram or ultrasound) is a prenatal test that is offered to most pregnant women. Use sound waves to show an image of your baby in the uterus (womb). Ultrasound helps your healthcare professional control the health and development of your baby.
Ultrasound can be a special part of your pregnancy because it is the first time you will “see” your baby! Depending on when it is done and your baby’s position, you may be able to see your baby’s hands, legs, and other body parts.
Most women have an ultrasound in the second trimester, between 18 and 20 weeks of pregnancy. Some pregnant women also have an ultrasound in the first trimester (called early ultrasound) before 14 weeks of pregnancy. Talk to your health professional to find out when it is right for you to have an ultrasound in Delhi.
What are some reasons to get an ultrasound?
Your professional uses ultrasound to do several things, including:
- Confirm (make sure) that you are pregnant
- Control the age and growth of your baby. This helps your professional calculate the expected date of delivery.
- Control your baby’s heart rate, muscle tone, movement, and overall development
- See if you are pregnant with meals, triplets or more (also called multiple )
- Perform screening tests for birth defects, such as spina bifida or heart defects. Screening means seeing if your baby is more at risk than others of having a health disorder; it does not mean to find out with certainty that your baby has the disorder. After the ultrasound, your provider may want to do more tests, called diagnostic tests, to determine with certainty if your baby has a birth defect. Birth defects are health problems that the baby has when he is born. These defects change the shape or function of one or more parts of the body. They can cause problems in general health, in how the body develops or how it works.
- To complement other prenatal tests, such as chorionic or placental villus sampling
- To examine the ovaries and the uterus (womb). The ovaries are the organ where the eggs are stored in the body.
- To check for complications of pregnancy, including ectopic pregnancy, molar pregnancy, and spontaneous abortion
Are there different types of ultrasound?
Yes. The type of ultrasound scan in Delhi done will depend on what you want to check your health professional and how many weeks of pregnancy you have. All ultrasounds use a device called a “transducer” that emits sound waves to create images of your baby on a computer. The most common types of ultrasound are:
- Transabdominal ultrasound. When you hear about ultrasound during pregnancy, it is most likely this type of ultrasound. You lie on your back on the examination table and your practitioner covers your abdomen with a thin layer of gel. The gel helps sound waves move more easily to achieve a better image. Then the radiologist in central Delhi moves the transducer through his abdomen. You may have to have a full bladder during the test because the sound waves move more easily by liquid than by air. Ultrasound pregnancy scan in Delhi is painless, but it can be uncomfortable to have a full bladder. The ultrasound lasts about 20 minutes.
- Transvaginal ultrasound. This type of ultrasound scan in Delhi is done through the vagina (birth canal). You lie on your back on the examination table with your feet in the stirrups. Your radiologist in Delhi inserts a thin transducer into your vagina. You may feel some pressure from the transducer but it should not cause pain. You must have your bladder empty or only partially full. This type of ultrasound also takes about 20 minutes.
In special cases, a sonologist in Delhi can use these types of ultrasounds to get more information about your baby:
- Doppler ultrasound. This type of ultrasound is used to check the baby’s blood flow if it is not growing normally. Your provider uses a transducer to listen to your baby’s heart rate and to measure the blood flow in the umbilical cord and some of your baby’s blood vessels. You may also have a Doppler ultrasound if you have Rh intolerance. This is a blood disorder that can cause serious problems for your baby if left untreated. Doppler ultrasound is usually done in the last trimester, but it can be done earlier.
- 3-D Ultrasound Three-dimensional ultrasound takes thousands of images at the same time. Create a three-dimensional image (3-D) that is almost as clear as a photograph. Some professionals use this type of ultrasound to make sure that your baby’s organs are growing and developing normally. You can also do a three-dimensional ultrasound to see if there are problems in the uterus.
- Ultrasound 4-D. It’s similar to 3-D ultrasound, but it also shows your baby’s movements in a video.
Does ultrasound have risks?
Ultrasound is safe for you and your baby when your the best radiologist in Delhi does. Because ultrasound uses sound waves instead of radiation, it is safer than X-rays. Professionals have used ultrasound for more than 30 years, and have found no dangerous risks.
If your pregnancy is healthy, ultrasound is useful to rule out problems, but not so good to find them. It may not detect some birth defects. Sometimes, routine ultrasound may suggest that there is a birth defect when there really is not. Although follow-up tests usually confirm that the baby is healthy, these false alarms are a concern for parents.
You may know some places, such as stores in shopping centers, that are not run by doctors or other medical professionals, who offer “3-D” or “4-D” images or videos of “remembering” ultrasounds for parents. Medical professionals do not recommend these non-medical ultrasounds. People who make them may not have medical training and may be given wrong or even harmful information.
What happens after an ultrasound?
For most women, ultrasound shows that the baby is growing normally. If your ultrasound is normal, just try not to miss your prenatal visits.
Sometimes ultrasound may show that you and your baby need special attention. For example, if the ultrasound shows that your baby has spina bifida, it may be treated in utero before birth. If the ultrasound shows that your baby is in a breech position (with feet down instead of upside down), your provider may try to turn the baby upside down, or you may have a cesarean section. Cesarean section is an operation in which your baby is born through a cut that the doctor makes to you in the abdomen and uterus.
Whatever the ultrasound shows, talk with your provider about the best care for you and your baby.
