Ultrasound FAQs

Q: Can you tell me the sex of my baby?

A: If the baby is in a good position for the sonographer to see the genital region, the baby’s sex can be determined. The sex can be determined as early as 14 to 16 weeks, although it may not be clearly visible until 20 to 22 weeks.

Q: Does a breast ultrasound show more than a mammogram?

A: Mammography is still the best way to image the entire breast. Ultrasound is used to target certain areas in question on the mammogram, as well as lumps and painful areas that the patient or physician is concerned about.

Q: Why do you have to have a full bladder for a pelvic ultrasound?

A: A distended bladder acts as a “window” through which the sound waves travel and allows the sonographer to visualize the pelvic organs. A distended bladder also displaces bowel, which can prevent visualization of the pelvic organs.

Q: Why do I have to fast for an abdominal ultrasound?

A: Fasting reduces the amount of air in the stomach and intestines which can interfere with visualization of the abdominal organs. It also ensures that the gallbladder will be distended so it can be thoroughly evaluated.

Q: How and when will I get the results of the exam?

A: Your doctor should receive a written report in 2 to 3 business days. If requested by your physician, a report can be called to him/her the day of the exam. You can get the results from your doctor.
