Diagnostic Ultrasound Imaging

If your doctor recommends an ultrasound, you’re in good hands at Banner Health. Our experienced imaging teams use advanced ultrasound technology to capture clear, real-time images to help guide diagnosis and care. Whether you're coming in for a routine ultrasound exam or need a more specialized procedure, we’ll help you feel prepared and supported every step of the way.

What is an ultrasound?

An ultrasound, also called sonography, is a diagnostic medical test that uses high-frequency sound waves, not radiation, to create images of the inside of your body. The sound waves travel through the body and bounce off soft tissues, internal organs or denser surfaces. These sound echoes are then converted into live images, called sonograms, on a screen.

This safe and noninvasive imaging method is used to monitor, diagnose or evaluate a variety of medical conditions.

What are ultrasounds used for?

Although most people associate ultrasounds with pregnancy, they are used for much more than just viewing the uterus and ovaries. Diagnostic ultrasound is used to examine internal organs, detect abnormal growths or masses and assess blood vessels for blockages or poor circulation.

Common types of ultrasound imaging include:

  • Abdominal ultrasound – To look at the liver, gallbladder, pancreas, kidneys and more
  • Breast ultrasound – To investigate a lump or follow up on a mammogram
  • Thyroid ultrasound – To assess thyroid nodules or enlargement
  • Kidney stone ultrasound – To check for stones or blockages in the urinary tract
  • Doppler ultrasound – To measure blood flow in blood vessels
  • Transrectal ultrasound – Often used to evaluate the prostate

The type of ultrasound you receive will depend on the type of symptoms or concerns your doctor is evaluating.

How to prepare for an ultrasound exam

Most ultrasound exams need little to no preparation. In some cases, you may be asked not to eat or drink for up to 12 hours beforehand. Your doctor will give you clear instructions based on the type of ultrasound you’re having.

To help ensure comfort during the exam, we recommend:

  • Wearing loose, comfortable clothing
  • Asking in advance if you should eat or drink before the test
  • Arriving early to allow time for check-in

What to expect during an ultrasound

During your ultrasound examination, a trained technologist will apply a clear gel to the skin over the area being studied. This gel helps a hand-held device, called a transducer, glide over your skin and send ultrasound waves into your body.

The process is generally considered to be safe and is not painful, though you may feel slight pressure if the technologist needs to press the transducer more firmly. The gel might feel cool when first applied.

Most ultrasound imaging tests take about 30 minutes or less.

Are there any risks?

Ultrasounds are generally considered to be safe. They do not expose you to ionizing radiation, unlike X-rays or CT scans. There are no known long-term side effects from ultrasound waves used in medical imaging.

Frequently asked questions about ultrasound exams

How long does an ultrasound take? 

Most ultrasound exams take about 30 minutes or less, depending on the area being examined.

What is the difference between a diagnostic ultrasound and a Doppler ultrasound?

A diagnostic ultrasound creates images of internal organs and soft tissues, while a Doppler ultrasound checks blood flow in blood vessels to look for blockages or narrowing.

Can I eat or drink before an ultrasound?

It depends on the type of ultrasound. Some require you to avoid eating or drinking for several hours. Always follow your doctor’s instructions.

Is ultrasound imaging safe?

Yes. Ultrasound exams are generally considered to be safe because they do not use radiation like X-rays or CT scans.
