PI: Amanda Lewis, PhD

CERVICAL DOPPLERS IN PREGANCY
PI: Jeffery Dicke, MD • RA: Lyndsay Roy
We hypothesize that cervical Doppler studies will reflect vascular remodeling during pregnancy and thus may be a useful tool
to assess cervical softening and dilation in pregnancy. As the cervical artery undergoes vascular changes throughout gestation to
enhance blood flow to the cervix, the intravascular resistance will decrease and the Doppler indices, including the S/D ratio and the
PI ratio, will decrease. We hypothesize that cervical Doppler indices will progressively change throughout each trimester. A total of
100 women will be enrolled in the Obstetric Ultrasound department in the Center for Advance Medicine.

OHP is predictive of therapeutic failure (recurrent preterm delivery). A total of 410 women will be recruited between 17 and 23
weeks gestation from the Obstetric Ultrasound department in the Center for Advanced Medicine and BJH.
