Fetal ultrasound provides you and your doctor with a first glimpse of your developing baby for due date clarification and anatomy evaluation.


Quick Facts

  • A safe, painless and non-invasive test
  • Typically performed between:
    • Dating Ultrasound – 6-12 weeks of pregnancy
    • First Trimester Screening (optional) – 10-13 weeks of pregnancy
    • Second Trimester Detailed Anatomic Screening - 18-22 weeks of pregnancy
  • Used to confirm a pregnancy and its location
  • Used to determine how a pregnancy is progressing, the baby's growth rate, age and sex.
  • Used to determine location and development of the placenta
  • Identifies possible fetal abnormalities


This type of ultrasound is used to evaluate the uterus, fallopian tubes and ovaries.

How To Prepare

  • Wear comfortable, loose-fitting clothing.
  • Most likely the test needs to be done with a full bladder.
  • For transvaginal ultrasound or those in late pregnancy, a full bladder usually isn't necessary.

What To Expect

  • The examination usually takes less than 30 minutes. 
  • The patient is usually positioned on an examination table and clear gel is applied to the abdomen. 
  • A transvaginal ultrasound may be performed to see the ovaries better, or to look more closely at the cervix or placenta in pregnancy.
