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 and Programs

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 and Pregnancy Program
The Mount Sinai South Nassau Diabetes and Pregnancy Program offers a comprehensive program for women who have any type of diabetes, from preconception to post-partum care. The program provides integrated obstetric and endocrine care by a team of high risk OBGYN Physicians, Certified Diabetes Care and Education Specialists, and nurses for women with gestational diabetes or either type 1 or type 2 diabetes.

The program allows pregnant moms access to advanced technology, such as insulin pumps and continuous glucose monitoring devices, in order to provide the ultimate level of care and management. All patients have access to a Certified Diabetes Care and Education Specialist and will receive one-on-one nutritional counseling.

The program also includes access to state-of-the-art diagnostic equipment to ensure optimal health for both mother and baby throughout the entire pregnancy. For more information about the Mount Sinai South Nassau Diabetes and Pregnancy Program, please call 516-632-4636.
