Shearwave Elastography

Shearwave Elastography is performed for Liver Assessment.

ClinRad Wynnum Plaza is pleased to offer a high quality, Bulk-Billed Shearwave Elastography service to our referrers and patients.

A Shearwave Elastography (SWE) assessment provides a quantitative measurement of the stiffness of the liver – somewhat similar to that of a traditional Fibroscan. This superior SWE technology is integrated into ClinRad’s Ultrasound systems and can simultaneously provide an assessment of the structural integrity of the liver, a technique that is not possible during Fibroscan. Through advanced visualisation technology, ClinRad sonographers are able to perform SWE with significantly increased accuracy and detail. SWE uses advanced ultrasound technology to create shear waves within the tissue. The displacement of the tissue caused by the passage of these shear waves is imaged and velocity calculated. The velocity is indicative of the tissue stiffness. Higher Velocity = High Stiffness. Shearwave Elastography can be referred for as part of an Abdominal Ultrasound, the patient preparation required is identical.

Shearwave Elastography is quick to perform to perform and a highly accurate report is produced. The skilled Sonographers at ClinRad have undertaken additional education and specialist training to ensure their images exceed industry standards. ClinRad is pleased to have a senior Sonographer currently completing their PhD in Shearwave Elastography and providing expert level advice and service to our referrers and patients.

A Shearwave Elastography report from ClinRad will include recommendations for interpretation of results, as suggested by Barr et al. (2020). Recommendations for interpretation of liver stiffness values obtained with ARFI techniques in patients with viral hepatitis and Non-Alcoholic Fatty Liver Disease:

Liver Stiffness Value Recommendation
≤5 kPa (1.3m/s) High probability of being normal
<9 kPa (1.7m/s) In the absence of other known clinical signs, rules out cACLD. If there are known clinical signs, may need further test for confirmation
9-13 kPa (1.7 - 2.1m/s) Suggestive of cACLD but need further test for confirmation
>13 kPa (2.1m/s) Rules in cACLD
>17 kPa (2.4m/s) Suggestive of CSPH
Note: cACLD = compensated advanced chronic liver disease, CSPH = clinically significant portal hypertension.
