Liver markers in UltraFast Ultrasound Imaging

SuperSonic Imagine innovates by introducing new markers which allow images to be associated with quantitative values. These measurements of fat content and tissue viscosity may help better manage patients with chronic liver disease.

Real-time ShearWave™ Elastography
ShearWave Elastography (SWE™) is a quick, non-invasive, reporducible exam that provides quantitative measurement and color-coded maps of the tissue stiffness on an anatomic B-Mode image. It can be performed on patients with ascites.

  • Can be performed in a hospital or private practice
  • Takes as little as 60 seconds
  • Provides imaging and liver stiffness quantification simultaneously

More than 160 publications have demonstrated the reliability and effectiveness of  SWE for the assessment of liver fibrosis in patients with chronic hepatitis B, C and NALFD.

B-Mode ratio
Hepato-renal contrast calculation can evaluate the level of steatosis;

Testimonials
« ShearWave Elastography is done identically to ultrasonography so it’s a very comfortable and simple exam for the patient and it takes only 30-90 seconds to perform. It gives us a qualitative and quantitative way to determine the degree of chronic liver injury our Hepatitis C patients have. We use it on a routine basis to help us make clinical decisions about how we treat patients and we think that by using this technique, we can cut down the number of biopsies by about half.»
Dr. James Trotter, MD of Baylor University Medical Center in Dallas, Texas, USA.
« As ShearWave Elastography is a real-time, non-invasive, reproducible method, it could have a significant impact on fibrosis detection, diagnosis
and disease follow-up. This could be helpful in validating the absence of fibrosis in order to reduce the number of unnecessary liver biopsies as well as to confirm cirrhosis to avoid dangerous biopsies and the possibility of hemorrhage. ShearWave Elastography could also guide biopsies, increasing tissue sample sensitivity.»
