Preparing for an Obstetrical Ultrasound
Prenatal ultrasounds conducted between 11 and 40 weeks do not require any preparation. Ultrasounds conducted prior to 11 weeks requires you drink between 250 ml – 750 ml of water one hour prior to your scheduled appointment, and do not urinate. This is essential, because it allows us to get a clear look at both the fetus and your reproductive organs. It is better to have full or semi-full bladder for these ultrasounds to evaluate baby’s cervical length.
What happens during an obstetrical ultrasound?
When you come in for your pregnancy ultrasound, a trained technologists will begin by applying a special gel to your abdomen. This gel is essential to help the sound waves travel smoothly. They will then use a handheld wand called a transducer over your abdomen, which sends high frequency sound waves into your body and back to the transducer. These sound waves are then turned into images that can be analyzed by a medical professional. Measurements may also be taken. For your comfort and convenience, images of your baby will be viewed on a monitor for you and your partner.
Early on in your pregnancy, you may also be given a transvaginal ultrasound, in order for the techs to get a clearer picture of the fetus. For this procedure, a small ultrasound probe will be inserted into the vagina to capture more detailed images.
