Background and study aims
Liver disease refers to a group of conditions which prevent the liver from working as well as it should do. The liver is the second largest organ in the body, performing a number of vital functions. It is responsible for removing toxins (poisons) from the body, releasing bile (a liquid that helps to break down fat during digestion) and helps blood to clot. There are over 100 different types of liver disease, and there are often no obvious symptoms until the liver is already badly damaged. In most types of liver disease, the liver becomes extensively scarred (fibrosis), which if left untreated can lead to complete liver failure. Although a biopsy (taking a tissue sample) is often needed to diagnose liver disease, ultrasound scanning is also widely used in diagnosis and monitoring. This is a safe and painless procedure that uses the way sound waves bounce off different types of tissue inside the body to produce a picture on a screen. Transient elastography (TE) is a scanning technique used to measure the stiffness of the liver. A probe placed on the skin produces a wave of vibration called a ‘shear wave’. The time that it takes for this wave to travel to a particular depth in the liver is measured and used to calculate the liver stiffness. If the liver is scarred (fibrosis), then it takes longer for the shear wave to travel through the tissue. Fibroscan (an ultrasound machine made by Echosens) is currently the best technique for detecting liver disease (gold standard), however there are other ultrasound systems available. This study will determine the reliability of Philips Affiniti Elast PQ Ultrasound System for the assessment of liver fibrosis, by comparing it to two other systems (Siemens ARFI Acuson S2000 Ultrasound System and the Fibroscan system made by Echosens).

Who can participate?
Adults with long-term (chronic) liver disease who is about to have, or has recently had, a sample of tissue taken from their liver (biopsy).

What does the study involve?
All participants undergo three ultrasound scans of their liver using the Philips EPIQ 7™ Ultrasound System, the Siemens Acuson (ARFI) Ultrasound System, and by Echosens Fibroscan™ (which is currently the best technique – gold standard). The results of the three scans are then compared to liver biopsy results of the patients in order to find out which is the most accurate technique.

Scientific titleThe role of ultrasound shear wave elastography in the management of liver disease
Study objectivesThe aim of this study is to correlate liver stiffness assessed by the Philips EPIQ 7™ Ultrasound System, the Siemens Acuson (ARFI) ultrasound system, and by Fibroscan™ (which is currently the best validated technique), and compare the results of these 3 imaging techniques to histological results in patients with chronic liver disease of different aetiologies.

Intervention typeOther
Primary outcome measureTo correlate liver stiffness assessed by the Philips EPIQ 7™ Ultrasound System, the Siemens Acuson (ARFI) ultrasound system, and by Echosens Fibroscan™ (which is currently the best validated technique), and compare the results of these 3 imaging techniques to histological results in patients with chronic liver disease of different aetiologies.
Secondary outcome measures1. Cut-off values of the liver stiffness (LS) measurements that correlate to the histological fibrosis stage
2. Variations of the liver stiffness (LS) measurements correlated to different parameters
3. Quality parameters (IQR and SR) for the liver stiffness (LS) measurements
4. Ability of distinguishing non-alcoholic steatohepatitis (NASH) from non-alcoholic fatty liver disease (NAFLD)
