W hen Sarah Carter was pregnant with her first child, she started digging into the research on ultrasounds, scouring studies in mice and rats. Then, she heard something that compounded her concerns. After an ultrasound, a friend of a friend was told her fetus had a limb malformation. Carter decided to refuse every ultrasound while pregnant. To her, the idea of spending her pregnancy anxious about ultrasound results seemed risky — riskier than the chance of missing something rare, but important, on a standard scan.
When her birthing center told her an ultrasound was mandatory to deliver there, she found a new provider. Ultrasounds are key to screening for serious developmental problems — including some that can be addressed in utero. Ultrasound results can dictate whether a woman needs to give birth at a certain kind of facility, so that specialists are on hand to care for the baby after birth. Prenatal care providers who spoke with STAT reported varying numbers of patients who refused ultrasound. Some often encountered skepticism, while others more frequently cared for women who were on the opposite end of the spectrum: getting far more ultrasounds than they needed at new standalone clinics that offer 3D and 4D scans.
All of them suggested the deviations from recommended scans were a new cause for concern. Ultrasounds use sound waves to capture images of a fetus inside the uterus. Many women have ultrasounds during the first trimester, which is helpful to estimate how far along a pregnancy is. Some women — including those with high-risk pregnancies or women carrying twins — have more scans.

This scan is carried out from 11 weeks to 13 weeks and six days. The scan is usually performed transabdominally but in a few cases it may be necessary to do.
Dating scans, which are often performed around the seventh week of pregnancy, were one of those interventions she said needed questioning. As soon as a pregnancy test returns a positive result, most women are able to work out when their baby is due using one of the numerous due date calculators on the internet or with the help of their GP.
Dating can be done at the nuchal translucency scan which can detect chromosomal abnormalities at about the twelfth week of pregnancy. The other is an anatomy scan, where a lot of important developmental problems can be picked up, around 20 weeks. While a pregnant woman might be eager to see that flickering heartbeat and reassure herself all was well with her bub-to-be, Ms Eddy said they should instead be guided by the usual early pregnancy symptoms such as nausea, fatigue and having tender breasts.
Rachael McEwing, a radiologist who is on the Maternity Ultrasound Advisory Group, said because unnecessary dating scans were being carried out, some women who really needed scans may not be able to get an appointment. Ministry of Health statistics show a trend for pregnant women to have more ultrasound scans over the past five years. In , the latest available figures, most had three to five scans.
Ms Eddy said another ultrasound women were too often being routinely sent for was a growth scan to check if the baby was bigger than normal. An ultrasound diagnosis of a baby being large for its gestational age is associated with an increased risk of the baby being delivered by caesarean. Dr McEwing said, like dating scans, unnecessary growth scans could result in a woman going on to have more scans.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder.
