Ultrasound Services
Ultrasound uses high frequency sound waves to create a 2D or 3D image of the uterus, cervix, placenta and fetus in order to monitor your pregnancy. They will typically be performed a handful of times throughout your pregnancy. They can be performed either abdominally or transvaginally. You may receive either a 2D or 3D ultrasound depending on your individual case and needs. Ultrasound can be used to evaluate fetal well-being, detect fetal anomalies and monitor your baby’s growth.

Maternal Fetal Medicine Additional Services

Genetic Counseling and Testing
Genetic counseling and testing, typically done through blood tests, provides information and support to women who are pregnant or planning to become pregnant to discuss possible genetic risks. By identifying these risk factors, such as advanced maternal age, inherited illnesses and disorders, chromosomal disorders, congenital anomalies and recurrent miscarriages, we can create the best possible care plans for our patients. When needed, invasive procedures are available.

Diabetes Education
Managing your diabetes can be difficult, especially when you’re pregnant. By working with one of our Certified Diabetes Educators (CDE), you can get the support you need. Our professionals will help you understand the basics of managing your diabetes and provide medical and nutritional education that meets patients’ individual needs.

Pediatric Cardiology
If needed, we offer fetal echocardiography, a specialized ultrasound that allows the physician to see the structure and function of your unborn child’s heart, in order to detect possible congenital heart defects or disease.
