Maternal Fetal Medicine Program

Added Reassurance

For pregnant people with complex conditions, an added level of reassurance.

People with obstetrical risk factors due to age, family history, or previous medical concerns have access to a Mass General maternal fetal medicine specialist at Cooley Dickinson Hospital in Northampton.

Maternal fetal medicine specialists at Cooley Dickinson are available for office consultations for people who meet the criteria for high-risk pregnancies. They offer detailed anatomical survey ultrasounds (level 2 ultrasounds) and consultation for high-risk pregnancies. Appointments are offered at Cooley Dickinson hospital.

Maternal fetal medicine specialists also act as liaisons between Mass General’s and Cooley Dickinson’s obstetrics departments. As a leader in diagnostic ultrasound, Mass General was among New England’s first hospitals to offer first-trimester screening for Down syndrome and other chromosomal abnormalities.

I See You

One of the common uses of ultrasound imaging is to observe the growth of a fetus during pregnancy. Most pregnant people will have at least two sonograms during their pregnancy; one in the first trimester to determine a general date of conception, number of fetuses (especially in people using fertility treatments), and fetal heartbeat; and one at around 20 weeks where more discernible anatomy can be seen and sex determined (if desired).

People with more complicated pregnancies are sometimes advised to receive more frequent ultrasounds to monitor the health of the fetus, or the function of the placenta.

If you are pregnant and want to learn more about the benefits of ultrasound imaging, you can consult your physician, nurse practitioner or midwife about your specific needs.
