Frequently Asked Questions

What are the risks of ultrasound?

Ultrasound is a specialized exam using sound waves (not X-rays) to visualize your fetus. No radiation is involved. To learn more, please visit the American Institute of Ultrasound in Medicine (AIUM).

Who will perform an ultrasound?

Obstetric ultrasound at Johns Hopkins is AIUM-accredited and employs registered ultrasonographers or diagnostic medical sonographer candidates who specialize in the field of obstetrics and high-risk obstetrics. All scans are interpreted by one of our maternal-fetal medicine specialists. In most cases, study results are provided to the patient before departure from our division.

What do I need to bring to my appointment?
  • Please be sure to arrive at least 10 to 15 minutes prior to your scheduled appointment to allow time for registration.
  • Please have your referral and a current insurance card with you at the time of your visit.
  • Due to the size of some of our exam rooms and the concentration needed on behalf of your sonographer, and to ensure your privacy, we kindly ask that you limit your guests to two adults.
  • If you arrive late for your appointment, we unfortunately cannot guarantee that we will be able to accommodate you the same day. If you know that you are going to be late, please call ahead at 410-955-8976 so that we may discuss accommodations with you.
How long will the ultrasound take?

The length of your exam may vary depending on the type of exam being performed, the number of fetuses and fetal cooperation. For a singleton pregnancy, you may expect 45 minutes to an hour, which includes chart review, exam time, and exam review by your physician and the sonographer. Twins and higher-order multiples are allotted the proper amount of time needed to perform a complete exam. Please note that if there is an unexpected finding, your exam may take longer, and if the fetus is uncooperative, you may need to return on a different day to try to complete the study.

Will I need a full bladder for the ultrasound?

You will need a full bladder if:

  • You are less than 14 weeks pregnant.
  • You are having a CVS procedure.

Your bladder should to be partially full if:

  • You are between 14 to 28 weeks pregnant.

You do not need a full bladder if:

  • You are having amniocentesis.
  • You are more than 28 weeks pregnant.
Can I eat before my appointment?

It is fine to eat before your ultrasound, unless specifically instructed otherwise by a physician.

Can I get a digital recording of my baby?

Digital recording for nondiagnostic purposes is not performed, but keepsake still images of your fetus may be provided. Please be aware that fetal position, gestational age and maternal build may limit our ability to obtain optimal keepsake images.

Can I have a 3-D ultrasound of my baby?

While we do have 3-D/4-D ultrasound machines, they are reserved for cases in which there is a known or suspected fetal abnormality.

In the event of a fetal abnormality, 3-D/4-D technology may sometimes be beneficial, but the limitations of 3-D are often the same as 2-D. Therefore, this technology is used at the attending physician’s discretion.

The Food and Drug Administration cautions against the use of 3-D/4-D imaging for entertainment purposes. Click here to read the official statement of the American Institute of Ultrasound in Medicine regarding the use of 3-D/4-D technology.

Will I be able to find out the gender of my baby?

Depending upon gestational age, fetal position and maternal build, we may be able to tell you the sex we think your fetus will be, but please keep in mind that ultrasound is not 100 percent accurate in the fetal sex determination.

What is the fetal anatomic survey?

At 20 weeks of gestation, it is recommended that pregnant women have an ultrasound to confirm if the fetus is alive, measure growth, detect uterine or placental abnormalities, assess fluid volume, and image all fetal organ systems to detect any abnormalities.

What is a fetal growth scan?

At any point during your pregnancy or as routine practice, you may be asked to return after your 20-week anatomic survey to evaluate the growth of the fetus. We will evaluate the fluid volume, perform measurements of your fetus and image some major organ systems again if fetal position allows. We may also assess fetal blood flow when appropriate.

What will happen if a problem is detected during my ultrasound?

While most fetuses are structurally normal, some may have major or minor problems. In the event that we detect any abnormality, you will speak with a maternal-fetal medicine specialist prior to departure from our division. Please note that there are limitations to ultrasound, and not all fetal abnormalities can be detected prenatally.

What if a student asks to perform part of my ultrasound?

The Johns Hopkins Hospital prides itself on the clinical education provided to our students, including diagnostic medical sonography students, medical students, residents and fellows in training. While we hope that you will take part in their education, we understand if you have reservations and respect your right to refuse. Regardless of your choice, the quality of your exam will not be impacted, and a trained, registered sonographer will thoroughly evaluate your fetus.
