Contrast Ultrasound: What It’s Used For, and 4 Key Advantages

Contrast Ultrasound: What It's Used for, and 4 Key Advantages

If you need imaging of your liver, kidneys, or bladder, your doctor might order an MRI or CT scan. But there is an alternative which doesn’t expose you to radiation (like a CT scan) or require you to lie still in an enclosed space (like an MRI): contrast-enhanced ultrasound.

At UVA Radiology and Medical Imaging, contrast ultrasound can replace other imaging tests for your liver or urinary system. Learn about how this safe and painless procedure is performed and 4 key advantages it holds over other imaging tests.


Ultrasound and Contrast: Working Together for Your Health

Contrast-enhanced ultrasound (or CEUS) brings together two imaging tools: ultrasound and contrast agents. The combination of these two techniques creates accurate, detailed images of internal organs. Here at UVA Health, CEUS can replace CT scans or MRIs of your liver, kidneys, or bladder.

Ultrasound is a safe and painless procedure that produces real-time images of the inside of your body using sound waves. It’s non-invasive, has no known side effects, and doesn’t use radiation.

During an ultrasound, a technologist guides a small probe over your skin. A warm gel is applied to your skin to make sure there are no air pockets between your skin and the probe. The technologist will move the probe around to get multiple images of the organ being examined. It usually takes only 20-30 minutes for the technologist to get all the images they need.

A special kind of contrast is used for contrast-enhanced ultrasound which is made up of gas-filled microbubbles. Midway through the ultrasound, this contrast is injected into your blood vessels through an IV line. This allows the technologist to take images both with and without contrast. Once injected, these tiny bubbles travel to your organs and make the organs much more visible on ultrasound.

The contrast solution used for CEUS at UVA is called Lumason. It’s been safely used in imaging of the heart for many years, and the likelihood of allergies to this contrast is rare compared to either MRI or CT contrast. A single injection of this contrast is equivalent to only a few drops of liquid. And after about 10 minutes in the body, the microbubbles harmlessly pop.

What Contrast-Enhanced Ultrasound is Used For

At UVA, contrast ultrasound is used to image the liver, kidneys, and bladder. The contrast agent we use is approved in the United States by the Food and Drug Administration (FDA) for use in examining both the liver and urinary system. In other countries, it is already being used safely to image other organs. 

The main reasons you would have a contrast-enhanced ultrasound are:

  • To get better-quality images of an abnormality seen on a regular ultrasound, CT scan or MRI
  • To monitor a known abnormality for changes in size or appearance
  • To monitor the liver for hepatocellular carcinoma (a type of liver cancer) in patients with cirrhosis (scarring of the liver)
  • To image the liver or urinary system in patients who are allergic to the contrast used in CT or MRI

4 Key Advantages

Contrast-enhanced ultrasound is safe and easy procedure, accurate at imaging internal organs, and more affordable than alternatives like CT scans or MRIs. Check out the following infographic to learn more about the key advantages of CEUS:
