Services OB Ultrasound

OB ultrasounds, also known as sonograms, are useful in helping us to detect potential problems, and to monitor your baby’s health throughout your pregnancy. Our ultrasound suites feature the latest technology, and we use our state-of-the-art ultrasound imaging for many reasons during your pregnancy:

  • To confirm your due date
  • To monitor the health of your baby, his or her growth, and position
  • To detect problems

Read: Preparing for Your Screening Ultrasound

Ultrasound refers to sound waves that are higher in pitch or frequency than the human ear can hear. These “sound” waves are transmitted, or sent, into the body via a transducers (probe) and are reflected off structures within the body. The reflections return to the transducer, are converted into an image by a computer, and are displayed on a monitor.

Depending on your medical history, there are several types of ultrasounds:

  • First trimester ultrasound
  • Screening ultrasound
  • Growth ultrasound
  • Limited ultrasound
  • Biophysical profile ultrasound

First Trimester Ultrasound
Your first trimester ultrasound helps us to accurately establish your due date, likely see your baby’s heartbeat, and evaluate your ovaries. It’s usually done using a transvaginal approach, where a special tool called a transducer is inserted into your vaginal canal.

Screening Ultrasound
An OB screening ultrasound is performed between 20 and 22 weeks to evaluate your baby’s health, growth, and environment. If the baby is positioned correctly, we are able to determine gender. Let your sonographer know if you’d like to learn the gender of your baby.

Growth Ultrasound
In certain situations, a growth ultrasound is performed in the second and third trimester to assure your baby is growing properly and that the amount of amniotic fluid surrounding the baby is adequate.

Limited Ultrasound
A limited ultrasound may be used to see baby’s heart beat, check baby’s position, check the location of the placenta, or check the amount of amniotic fluid surrounding your baby. It usually serves as follow up to a Screening Ultrasound.

Biophysical Profile Ultrasound
In certain circumstances, this ultrasound is used to check on your baby’s well-being by monitoring various movements of your baby and checking the amniotic fluid surrounding baby.

Accredited Ultrasound Facility

Our ultrasound department is an American Institute for Ultrasound in Medicine (AIUM) accredited facility. This means our practice has met accepted national standards and has shown consistent excellence in patient care when providing diagnostic ultrasounds. To become accredited, our staff has undergone rigorous and detailed testing and fulfilled the necessary requirements to become certified. State and federal laws do not require accreditation; however, our practice is, giving you piece of mind that we are qualified to perform your ultrasound examination.

Trained & Committed Sonographers

Our sonographers are registered with the American Registry of Diagnostic Medical Sonographers (ARDMS). This ARDMS registration assures our patients that we have consistently met high professional standards for sonographers, as well as achieved exceptional competency in patient care and technical procedures. To achieve this our sonographers have passed the ARDMS examinations and have fulfilled continuing education requirements to increase their knowledge and skill level.

Diagnostic ultrasound has been used for many years and there is little evidence suggesting that OB ultrasounds are harmful when used properly. Our sonographers are registered by the American Registry of Diagnostic Medical Sonographers (ARDMS) and have advanced training and longtime experience in sonography. They do their best to make this an enjoyable experience for you.

If you have questions or concerns, we encourage you to talk to your provider or talk to your ultrasound specialist.

Ultrasounds are performed at our Oakdale ObGyn clinics in Maple Grove, Blaine, Plymouth, and Crystal.

If you need advanced imaging studies, they are performed at the Perinatal Center at the North Memorial Outpatient Center at Maple Grove Hospital, and at North Memorial Medical Center. Our team will give you detailed instructions about how to prepare for your ultrasound and where to go.

Our sonography rooms feature state-of-the art technology and our sonographers are skilled at walking you step-by-step through the entire process. If you have questions at any point during your ultrasound, please ask.

Depending on your medical history, our trained sonographers may either insert a probe into your vagina (transvaginal approach) or use a probe on top of your tummy (transabdominal). Images of your baby will appear on a monitor.

  • Is ultrasound safe? There are no known harmful effects associated with the medical use of ultrasound. The American Medical Association as well as the American Institute of Ultrasound in Medicine strongly discourages the use of ultrasound without a medical purpose.
  • What can I expect to see on my first trimester ultrasound? At your first OB screening ultrasound, we’ll make sure that your pregnancy is located where it should be and the number of babies. You may see your baby’s heartbeat and receive a new due date. Your ovaries and other soft tissue will also be evaluated.
  • What can I expect to see during my second and third trimester ultrasound?
    You will learn how the baby is positioned, the location of the placenta, and the level of amniotic fluid. We’ll look at your baby’s anatomy and general health, and measure your baby’s growth.
  • Are there limitations to ultrasound of my baby? An OB screening ultrasound examination in pregnancy does not guarantee a normal baby. The ability of the ultrasound examination to detect problems with your baby depends on many things: the age of the baby at the time of the ultrasound, the position of the baby, and your body size. Some problems cannot be seen by ultrasound because they are too small or not even visible by ultrasound.
  • How many ultrasounds of my baby will I have? Most moms-to-be only need one ultrasound during their pregnancy. However, your provider may recommend additional exams to help monitor your baby’s health.
  • Will I get ultrasound pictures of my baby? After the sonographer has completed the exam, she will give you pictures of your baby; printed and also texted to your cell phone where you can save them and/or share them with your favorite social media site. Video taping, cameras, cell phones, or other recording equipment are not allowed in the ultrasound exam rooms.
  • Will I find out the sex of my baby? Maybe. Sometimes it isn’t possible to determine the gender due to baby’s position or age. Ultrasound exams are not done for gender determination.
  • Can I bring my family and/or friends to my ultrasound examination? Yes, but please keep in mind that the ultrasound is a medical examination. The sonographer requires a quiet, respectful atmosphere in which to concentrate on performing the exam. Also, be advised that the ultrasound rooms are relatively small and are dimly lit.
