Liver disease is a serious problem in the UK. Accurately diagnosing liver fibrosis (scarring) and inflammatory activity are the most important factors for determining the stage of the disease, assessing the patient’s prognosis and predicting treatment responses.
Here, leading London gastroenterologist Dr Aathavan Loganayagam explains everything that happens during a liver FibroScan®.
Which liver diseases can a FibroScan help to assess?
A liver scan may help to determine a wide range of diseases, including viral hepatitis B and C, fatty liver disease, drug-induced and alcohol liver injury, primary biliary cirrhosis, and autoimmune hepatitis.
What is a liver fibrosis scan?
A liver FibroScan® (ultrasound-based elastography) is a non-invasive and painless approach for assessing fibrosis in liver disease.
The use of non-invasive tests to stage the severity of liver disease (i.e. scarring) is now well established in the management of patients with chronic liver disease.
This is because the assessment of liver scarring provides prognostic information and assists in establishing treatment priorities. One such technique, shear-wave elastography, is a simple, safe and efficient way to estimate liver scarring.
When performed in the appropriate clinical setting, elastography proves to be a reliable method of detecting cirrhosis and excluding significant fibrosis, particularly when the results are supported by clinical and laboratory data.
How is the test performed?
With the patient lying supine, an ultrasound probe is placed on the skin over the liver area, which is in the right mid-axillary line. Typically, the test takes around 10 minutes to perform and causes no patient discomfort. In general, patients should have fasted for at least two hours before the procedure.
What are the indications for this test?
A fibrosis scan is principally used to estimate the degree of liver scarring present (i.e. stage of liver disease). This is very useful in the assessment of patients with chronic liver disease, including chronic hepatitis C, chronic hepatitis B, fatty liver disease and chronic alcohol abuse.
The concept is that as more fibrosis and scarring occur, the higher the liver stiffness reading will be. This reading may be used to:
