A pelvic ultrasound uses sounds waves to assess organs and structures within the female pelvis, including the uterus, cervix, vagina, fallopian tubes and ovaries. An obstetric ultrasound produces pictures of a baby (embryo or fetus), as well as the mother's uterus and ovaries. St. James has invested in new machines that include all the technological advances in obstetric ultrasound imaging. We are able to capture 3D images of your baby. Our technology does not use ionizing radiation, has no known harmful effects, and is the preferred method for monitoring pregnant women and their unborn babies. The Women's Imaging and Breast Center accommodates all OB patients.
