Hill says that skeptics point to animal models in which an increase in fetal temperature from the ultrasound waves has been related to birth defects. These findings from animal models have never been seen in humans. Ross says ultrasounds are performed in the first trimester to evaluate an early pregnancy and establish the dating of the pregnancy.
You can also count on an ultrasound between 16 and 20 weeks to assess the structural anatomy of the fetus as well as its sex if you want to find out. However, depending on your insurance plan, you may have to pay for the scan as part of your deductible. The cost also depends on where you get an ultrasound and in what region. Whereas you can visit your local Planned Parenthood health center for low-cost ultrasounds whether you have health insurance, or not.
That's according to the free online tool HealthcareBluebook, which collects prices from large health plans nationwide. You can look up cost estimates for your specific area on HealthcareBluebook. While most women can expect at least two ultrasounds during pregnancy — in their first and second trimesters respectively — there are many reasons why your doctor may advise for more.
Ultrasound exams are important when monitoring the development of your baby, and it's normal to feel anxiety with the idea of needing more screenings beyond the routine checkups. Be sure to ask your healthcare provider questions, as well as for resources pertaining to any unforeseen issues that may arise.

Women's Health. Primary Care. Many parents-to-be don't need an ultrasound in the third trimester. But if your pregnancy is considered high-risk—for example, if you have high blood pressure, bleeding, low levels of amniotic fluid, preterm contractions , or are over age 35 —your doctor may perform in-office, low-resolution ultrasounds during your prenatal visits for reassurance, says Dr.
You'll also get a follow-up ultrasound if your cervix was covered by the placenta at your week scan. A regular ultrasound uses sound waves to produce images; this one bounces high-frequency sound waves off circulating red blood cells to measure blood flow and blood pressure. The test will determine if your baby is getting enough blood.
Your provider may also conduct other pregnancy tests that require ultrasounds. These might include chorionic villus sampling CVS or amniocentesis. Fetal echocardiograms, which show the baby's heart rate and detect abnormalities, also use ultrasound technology. An ultrasound is considered safe for both you and your baby when it's used for medical purposes. Although ultrasounds require no radiation, only a trained professional who can interpret the results with accuracy should perform them.
Your technician should be schooled in obstetrical ultrasound, preferably at a center accredited by the American Institute of Ultrasound in Medicine.
Some medical practices now offer 3D high quality and lifelike and 4D moving picture ultrasounds, which may help doctors detect certain fetal abnormalities and birth defects. However, these types of exams are also available at fetal portrait studios in places like shopping malls. Experts discourage these "keepsake" ultrasounds since untrained personnel may give out inaccurate information, says Michele Hakakha, M. Plus, although ultrasounds are safe in medical settings, they might heat tissues or produce bubbles cavitation during use.
The ultrasound technician will put warm ultrasound gel on your stomach and then slide the transducer in the gel around your stomach. The gel helps the sound waves travel through your skin. Tip: Come to your appointment with a relatively full bladder. This will make it easier for your ultrasound technician to get better images of your baby.
Because there are so many things to look for, this ultrasound will take at least 45 minutes—if your little one cooperates! During the full anatomy, week ultrasound, you can find out if your baby is male or female. When the scan is complete, Meriter will even send you a link to view some fun photos of your baby! After your ultrasound technician has captured all these images and measurements, your OBGYN will review the pictures and look for abnormalities such as congenital heart defects or cleft lip or palate.
In the meantime, you can enjoy those 2D or 3D photos of your baby! Sometimes, women need additional ultrasounds during pregnancy. One way doctors estimate whether your baby is growing as expected is by measuring your fundal height. Fundal height is the number of centimeters from your pubic bone to the top of your uterus.
This measurement typically increases about 1 cm each week. If your uterus has not grown appropriately in the last month, your OBGYN will surmise that your baby is also not growing and will want to perform monthly growth ultrasounds.
These ultrasounds take less time than the full basic anatomy ultrasound because there are fewer measurements required.
