Most healthy women receive two ultrasound scans during pregnancy. "The first is, ideally, in the first trimester to confirm the due date, and the second is at 18-22 weeks to confirm normal anatomy and the sex of the baby," explains Mendiola.
During the third trimester of pregnancy, ultrasound is commonly performed in patients that present both asymptomatically or with symptoms. There are currently no major guidelines or protocols to standardize the use of ultrasound at this stage of pregnancy.
When is ultrasound offered to pregnant women? Most women will be advised to have at least two ultrasound scans during their pregnancy — the first and second trimester scans.
Most women get an ultrasound in their second trimester at 18 to 20 weeks of pregnancy. Some also get a first-trimester ultrasound (also called an early ultrasound) before 14 weeks of pregnancy. The number of ultrasounds and timing may be different for women with certain health conditions like as asthma and obesity.
Your First Ultrasound
It's typically done between 7 and 8 weeks to verify your due date, to look for a fetal heartbeat, and to measure the length of the baby from “crown to rump.” At this ultrasound, you'll also learn whether you're having one baby, pregnant with twins, or more!
More and more obstetricians refer women for two third trimester ultrasounds, mostly at 28 weeks and 36 weeks, because there is increasing evidence that this allows better detection of growth problems and ensures better outcomes for babies.
Medicare can cover all or part of the health care costs of having a baby, including your doctor and midwife visits, ultrasound and blood tests, and having your baby in an approved facility. Your state or territory government may also help to pay some of the costs of services after your baby is born.
Common Reasons For Repeat Ultrasounds. If there is an abnormality noted on the anatomy scan or your baby's position wouldn't allow for complete visualization of all vital organs, you may have to repeat just the portion of the anatomy scan that assesses the organ in question.
Fortunately, the American College of Obstetricians and Gynecologists (ACOG) states that there is no current evidence that ultrasounds pose any risk to an unborn baby. "No links have been found between ultrasound and birth defects, childhood cancer, or developmental problems later in life," the ACOG adds.
So Why Is it So Important to Drink Water Before an Ultrasound? Dehydration can cause your urine to be concentrated, which can lead to inaccurate results. In addition, dehydration can also cause the liver to produce less bile, which can make it more difficult to see the gallbladder on an ultrasound.
Anatomy scan (18–22 Weeks)
According to ACOG, this detailed pregnancy ultrasound generally happens between weeks 18 and 22 in the second trimester. It's the most thorough check-up your baby will have before they're born.
This scan allows us to check how your baby is developing and in combination with a blood test allows us to check for any genetic concerns. This scan should be ideally performed between 12 weeks 5 days and 13 weeks 6 days of your pregnancy.
Determination of fetal presentation.
Through the ultrasound, the sonographer can confirm whether the unborn baby is in the proper position for birth -- head down toward the pelvis.
While many moms choose to come to our studio multiple times during their pregnancy to watch the baby grow, we recommend 28 – 33-week ultrasound scans for those chubby cheek face shots! The majority of our pregnant moms come for this particular baby ultrasound right around that 32-week mark.
During the third trimester, some offices perform ultrasounds every two weeks, while others (like ours) perform one every three to four weeks. To be clear, we are talking about ultrasounds that evaluate fetal growth and amniotic fluid volumes, not ultrasounds that look at fetal activities such as movement and breathing.
“A review of over 50 medical studies shows that ultrasounds do not pose any danger to moms or fetuses. They do not cause birth defects, childhood developmental or intellectual problems, or cancer.”
You will have at least two ultrasounds during your early and middle pregnancy, and in the later parts of your high-risk pregnancy, you may have ultrasounds as often as once a week based on your health needs and situation.
LEVEL-3. Colour Doppler Scan (About 28-32 wks): Doppler Ultrasound gives doctors a visual or audible representation of blood movement through veins, arteries and blood vessels with sound waves. The reflected sound can be used to diagnose restricted blood flow, blood clotsand fetal health.
Except for item 55758, Medicare benefits are not payable for more than three NR-type ultrasound services in Subgroup 5 of Group I1 (ultrasound) that are performed on the same patient in any one pregnancy.
