Maternal Fetal Medicine Ultrasound

With advances in technology, ultrasounds are no longer grainy images. The Center for Genetics and Maternal Fetal Medicine (CGMFM) has state of the art ultrasound systems — including 3D/4D ultrasound — to provide detailed views of your baby.

CGMFM is accredited by the American Institute in Ultrasound Medicine (AIUM) in fetal echocardiography, as well as in 1st, 2nd, and 3rd trimester obstetrical ultrasound. This achievement followed a comprehensive practice assessment which determined that CGMFM staff, policies, equipment, procedures, and more meet the rigorous AIUM criteria.

The perinatal sonographers at CGMFM are registered by the American Registry for Diagnostic Medical Sonography (ARDMS), with specializations in neurosonography, fetal echocardiography, and obstetrics and gynecology. They are also licensed by the state of Oregon.

TYPES OF EXAMS

TYPES OF EXAMS

    • First Trimester Ultrasound: In the first trimester, we are able to assess how far along you are (gestational age), if the baby’s heart is beating (viability), and perform a basic anatomic survey depending on gestational age. It is helpful for your bladder to be moderately full for this exam.
    • Nuchal Translucency Measurement: This measurement of the fluid in the back of the fetal neck is used to screen for chromosomal abnormalities like Down syndrome. Providers who perform nuchal translucency ultrasound for Down syndrome screening are required to have specialized training.  All of sonographers and physicians at CGMFM are certified by the Nuchal Translucency Quality Review.  It is helpful for your bladder to be moderately full for this exam.
    • Detailed Anatomy or Level 2 Ultrasound: In the second trimester we obtain a detailed view of the internal organ systems of your baby, as well as measurements. This provides information about your baby’s development. The detailed protocol we follow is approved by the American Institute of Ultrasound Medicine. You do not need to have a full bladder for this 2nd or 3rd trimester ultrasound exam.
    • Fetal Echocardiography: A fetal echocardiogram is a detailed ultrasound of your baby’s heart. We look at the chambers, valves, and vessels. Fetal echocardiograms are performed for various reasons and are not required on all babies. This exam is performed when a baby is at increased risk to have a heart malformation. You do not need to have a full bladder for this exam.
    • Biophysical Profile and Non-Stress Test: In the third trimester, your physician or the CGMFM physicians may request testing to make sure your baby is not under stress. Our nurse may perform a Non-Stress Test (NST) or you may have a Biophysical Profile (BPP). The NST monitors the heart rate and activity of the fetus. The BPP is an ultrasound exam that evaluates amniotic fluid, fetal tone, breathing and activity. Either or both tests may be performed.

YOUR MATERNAL FETAL MEDICINE ULTRASOUND

  • Most sonograms are performed by abdominal ultrasound (on top of your skin).  In some cases, a vaginal ultrasound allows us to better visualize of the details of the baby or the mother’s cervix.
  • Safety:  Although there is no evidence that fetal ultrasound is harmful to the developing baby, we will limit your baby’s exposure to unnecessary sound waves by obtaining images efficiently.
  • Friends and Family: While we encourage patients to bring a support person to their ultrasound exam, please consider that it can difficult to have children at the exam for many reasons.
  • Pictures and Videos: We will provide images of the baby. We have a policy against videotaping the ultrasound exam.
  • Our ability to obtain images is affected by fetal position and scanning characteristics of each patient.
  • On the day of the procedure, it would be best to wear a 2-piece outfit.  You can eat normally before your appointment. You do not need to drink additional water before the appointment.
  • Please allow extra time, at least 15 minutes, for parking in the multistory garage and walking into the building.
  • The care providers at CGMFM are committed to excellence in ultrasound in medicine.
