ShearWave™ Elastography Accurately Assesses Liver Fibrosis in Patients with Chronic Hepatitis B
Ultrasound (US) imaging plays a major role in the global management of patients with chronic liver diseases. Thanks to its wide spectrum of clinical applications, ultrasound collects valuable information for diagnostic purposes, patient follow-up, and therapeutic decision-making

The quantification of hepatic fibrosis is of critical importance in the management of patients with chronic Hepatitis B infection, as it impacts the treatment indication.

SWE in the liver provides an accurate correlation between liver elasticity and liver fibrosis staging, and SWE in the spleen may serve as an ancillary parameter in advanced fibrosis. Real time SWE is found to be easy to perform with reproducible, quantitative measurements. It has been integrated into a conventional ultrasound machine, Aixplorer®, and can be performed in the same setting of morphological evaluation of liver cirrhosis and associated complications. Together with hematological and biochemical examination, physicians are provided with a more comprehensive assessment of the fibrotic status of the liver and the spleen in chronic Hepatitis B patients. Early and correct detection of METAVIR stage F2 liver fibrosis is very important, as antiviral and/or anti-fibrotic treatment can be started in a timely manner, thus preventing the progression of fibrosis. SWE is also valuable for longitudinal investigations and for the monitoring of treatment response, particularly for patients with contraindications to liver biopsy.

The advantages of real time scanning, superb resolution, repeatability, reproducibility, quantification and a high acquisition success rate make SWE a promising new technique in ultrasound elastography.
