What to expect

When you arrive for your appointment, your sonographer will explain the exam he or she will perform. He or she will ask you a few questions about your medical history to ensure we provide necessary information to the radiologist for interpretation. Our sonographers are not permitted to give results, but each ultrasound will be reviewed and read by a board-certified radiologist. The report will be sent to the physician that ordered your exam, and he or she will contact you with your results.

If you are having a right upper quadrant, liver, or gallbladder ultrasound, we ask that you have nothing to eat or drink up to 8 hours prior to your exam. This is to ensure we are obtaining the best possible imaging. It will reduce the amount of bowel gas present in your belly and will ensure your gallbladder is in the proper fasting state. This means it will not be contracted, which would limit its evaluation. If you are not properly fasted when you arrive for your exam, we will be happy to reschedule your appointment for another day so we can provide the best study possible.

For a transabdominal pelvic ultrasound, you must have a full bladder, which acts as a window to properly visualize your uterus and ovaries.

Prior to a transvaginal ultrasound, you will be asked to use the restroom and completely empty your bladder. For the exam, your feet will be in stirrups just like a routine pelvic exam performed by your doctor. An ultrasound transducer will be inserted a short distance into the vaginal canal to take very detailed pictures of your uterus and ovaries. You may feel some pressure.
