An ultrasound is an examination which uses high-frequency sound waves to create images.  Ultrasound does not involve radiation. A Registered Diagnostic Medical Sonographer will perform your exam.

Is there any preparation prior to the exam?

Preparation is required for some ultrasound exams.

Abdominal: This exam studies the organs in your abdomen (liver, gallbladder, pancreas, kidneys, spleen, aorta).  Please do not eat or drink anything after midnight of the day prior to your exam.

Pelvic or Obstetrical: Whether you are pregnant or not, you will be required to drink four 250 mL (8 ounce) glasses of water one hour before your appointment time. Please do not use the restroom until after the exam. Your bladder must be full in order to study the pelvic organs and, if you are pregnant, the anatomy of the baby. Your bowel lies in front of these structures/organs, and a full bladder will push the bowel away to allow a better view.

There are a number of other ultrasound exams that do not require any preparation.

What should I expect during my examination?

Depending on the type of exam, you may be asked to change into a gown. The Sonographer will ask you questions concerning your medical history and current symptoms that are important to your exam.  All exams are performed by applying a special gel to the area and moving a transducer over the area.

How long will my examination last?

Depending on the type of exam, it will last from 20-90 minutes.

Who reports my pictures?

The pictures are reported by our in house Radiologist.  The results are forwarded to your doctor.
