How to Prepare for Your Ultrasound Appointment
Ultrasound imaging technology allows healthcare providers to monitor fetal growth and screen for potential complications without using radiation. It is typical to have two ultrasounds done during pregnancy, but certain risks or family history may necessitate more. Ultrasound is a safe procedure for pregnant women and developing babies. Here is more information about what an ultrasound is and how to prepare for your appointment:
What Is an Ultrasound?
An ultrasound, sometimes called a sonogram, is a diagnostic medical test that uses high-frequency sound waves to create images of the inside of the body. A device called a transducer emits sound waves that bounce off internal structures, including the developing baby and reproductive organs. These returning echoes are then transformed into visual images on a screen, allowing the provider to see inside the uterus.
What Happens During the Appointment?
During your visit, the environment is typically dimly lit to help the sonographer see the images on the screen clearly. You will lie on an examination table; the technician will apply a water-soluble gel to your abdomen or the transducer itself. This gel might feel cold initially, and it helps the sound waves travel efficiently through the skin. You may be able to ask the technician if you can have a view of the screen as well.
The sonographer moves the transducer to capture various angles; they will likely take measurements of the baby’s head, abdomen, and bones. While the experience is generally painless, you might feel mild pressure as the technician guides the device to get the best view.
The ultrasound technician looks for several specific developmental markers to determine the health and development of the unborn baby:
- Gestational Age: determines how far along the pregnancy is.
- Fetal growth: checks if the baby is developing at the expected rate.
- Anatomy: examines organs like the heart, brain, and kidneys.
- Placenta Position: locates the placenta and checks amniotic fluid levels.
What Preparation Should I Do?
Preparation for an ultrasound is generally minimal. For abdominal ultrasounds, you may be asked to arrive with a full bladder. The patient having a full bladder helps the technician be able to view the baby better. Wear loose, comfortable clothing. Two-piece outfits are ideal because they allow easy access to your abdomen without the need to fully undress or wear a hospital gown.
You may be able to bring a support person, but check with your clinic beforehand regarding their specific guest policies. Because the appointment requires focus, it is generally discouraged to bring young children unless another adult is present to supervise them. If you are having a transvaginal exam, you will likely need to empty your bladder right before the procedure and undress from the waist down.
Learn More About Ultrasound Appointments
Ultrasounds are one aspect of modern prenatal care, offering a view of the developing baby to support the health of both mother and child. Whether confirming a due date or checking fetal development, these appointments provide medical data and images of your baby.
