What is an ultrasound and is it safe?

Ultrasounds are the utilizations of high frequency sound waves used to image particular organs in the body. In most cases, a sonographer trained in ultrasound obtains and records the images required for diagnosis. The Radiologist/physician reviews the images and then issues an official interpretation.

There are no known harmful effects associated with the medical use of sonography.

What will I experience during the procedure?

Once you arrive for your exam, you will be asked to lie down on an exam table. In some cases, you may be asked to change into a hospital gown before the exam.

  • The sonographer will apply warm gel to the part of your body being examined, then move an instrument called a transducer over the area(s) of interest to obtain specific images for the radiologist’s interpretation.
  • You may be asked to assume a series of different positions (i.e., lie on your side, sit up, etc.)
  • The results of all exams will be sent to the requesting physician, who will then communicate those results to you.
