This is a test during which high frequency sound waves are used to form images of your unborn baby and/or pelvic organs. Please do not bring small children to either of these exams.

OB ultrasounds are used to evaluate your unborn baby in order to:

• estimate the dating of a pregnancy
• diagnose abnormalities
• determine the position of the baby and placenta
• determine if there are multiple pregnancies
• evaluate the amount of amniotic fluid present
• determine the appropriate growth of the baby.

GYN ultrasounds are used to diagnose:

• ovarian cysts or masses
• fibroids in the uterus
• the cause of pelvic pain.

The Procedure
You will lie down on the exam table and a specially trained technologist (sonographer) will apply a lubricating gel to your abdomen. Next the technologist will move a handheld device called a transducer around your abdomen. If you are having a transvaginal ultrasound, a probe will be inserted a short distance into your vaginal canal using lubricating gel for comfort.
