If you are scheduled for an ultrasound at HWG, please take a look at the exam you are scheduled for below. A few of the exams require that your bladder be full when you arrive at the office. Please drink 20 oz of water 1 hour BEFORE you arrive. This can be vital in making sure we get adequate images.

Exams requiring full bladder

  • 1st Trimester OB
  • 2nd Trimester OB
  • NT (nuchal translucency) study
  • Pelvic Ultrasound

Exams that need no preparation

  • Biophysical profile
  • Cervical length only
  • Low lying placenta follow-up
  • 3rd Trimester OB follow-up

You may have up to two additional people with you in the ultrasound room. This room is quite small and seating is limited.

The patient will be given pictures of the baby to take home. No cameras or video recording devices are allowed in the room during the ultrasound exam. We also ask that you refrain from bringing food or drinks into the exam room. The pelvic, cervical length, and low lying placenta follow-up ultrasounds are performed transvaginal.

As a reminder we do send out all sonograms to Dr. O’Hara for reading so you will receive 2 separate billing statements for your ultrasound.

Thank you!
