Conditions Treated

Obstetrix MFM Imaging Center

The Obstetrix Maternal-Fetal Medicine Imaging Center performs low-risk radiological imaging for pregnant patients.

All ultrasounds are performed by a sonographer trained in obstetric ultrasound and read and reported by a Board Certified Maternal-Fetal Medicine Specialist. If an abnormality is discovered during the evaluation, our office will partner with the referring physician to coordinate a referral for the patient to one of our MFM practices for consultation if desired.
