About the Procedure

Ultrasound imaging, also called ultrasound scanning or sonography, is a method of obtaining images from inside the human body through the use of high-frequency sound waves. It is a popular diagnostic technique that has been used for many years. A small probe called a transducer is held to the skin as it sends out sound waves. These sound waves travel through the body and are reflected by internal organs back to the transducer and a computer to produce an image on the monitor screen. You cannot hear or feel these sound waves.

The main advantage of ultrasound is that certain structures can be observed without using radiation.



You should wear comfortable, loose-fitting clothing for your ultrasound exam. Other preparation depends on the type of examination you will have.

  • Abdominal and Abdominal Aorta Ultrasound:  No food or drink after 12:00am (midnight) prior to the exam. Early morning appointments are desired to encourage patient preparation and good patient care. Medication may be taken with only a small amount of water if necessary. If your appointment is in the afternoon, no food or drink is allowed 8 hours prior to the exam.
  • Renal/Bladder Ultrasound:  Do not void (empty bladder) one hour before the scheduled exam.
  • Follicle Study:  No preparation is necessary.
  • Venous:  No preparation is necessary.
  • Thyroid:  No preparation is necessary.
  • Scrotum/Testicular:  No preparation is necessary.
  • Carotid: No preparation is necessary.



A board-certified radiologist will interpret the scan and send a report to your referring physician within 24 hours. Anything needing immediate attention will be called to the referring physician the day of the exam. Your referring physician will contact you with your results.
