About the Exam:
Sound waves are used to examine internal organs. Obstetrical ultrasound is used to determine the baby’s age, position, appearance of body parts, volume of fluid around the baby, and the position of the placenta. An ultrasound technologist will apply a warm gel to the skin which allows the sound waves to be transmitted and received from inside the body. The images are recorded digitally. No radiation is utilized to produce the images.
One hour prior to the appointment, empty bladder and finish drinking 32 ounces of water or other non-carbonated beverage. Do not urinate until after your examination is complete. A full bladder is necessary.
