About

Aim: To use magnetic resonance imaging (MRI) scans without contrast to help improve diagnosis of liver cancer in people who are at increased risk of developing liver cancer.

Background: People with any condition that affects the liver over a long period of time can develop cirrhosis. Conditions and risk factors that can lead to cirrhosis include alcohol excess, liver steatosis (lipid or fat accumulation in the liver) and infection with the viruses hepatitis B and C. One of the concerns about people with cirrhosis is that they are at increased risk of developing liver cancer. People with cirrhosis are recommended to have an ultrasound scan (USS) every 6 months (surveillance for liver cancer) so that if a cancer develops, it is diagnosed at an early stage when it can be cured. However, ultrasound can miss cancers even in people having scans every 6 months. Furthermore, the risk of cancer is not alike among people with cirrhosis. For example, people with more advanced cirrhosis and those with cirrhosis from hepatitis B are at higher risk. It is therefore possible that better tests than ultrasound are needed for people with cirrhosis who are at particularly high risk of developing cancer.

Computed tomography (CT) and Magnetic Resonance Imaging (MRI) scans with dye injection (contrast) are used for liver cancer diagnosis. However, they cannot be done every 6 months because of costs, capacity and toxicity from high CT radiation doses, and MRI contrast build-up in the brain with repeated MRI contrast injections. MRI scans without contrast are not toxic, could be done in 20 minutes and are cheaper, so could be done every 6 months. In the experience of the study investigators, MRI without contrast may raise suspicion of liver cancer in cases missed by ultrasound, so it could be used for surveillance instead of ultrasound. This study aims to find out if it is feasible to use a quick MRI (20 minutes) without contrast as surveillance for liver cancer in people at high risk of liver cancer due to liver cirrhosis and to compare this MRI with ultrasound.

Design and Methods: The investigators will recruit 300 people at higher risk of developing liver cancer because of cirrhosis. Study participants will have an ultrasound scan every 6 months as they would in their standard clinical care and an additional 6 monthly non-contrast MRI scan for 30 months (6 visits). If the ultrasound or non-contrast MRI raises concern for a possible liver cancer, an MRI scan with contrast (with dye injection) will be done for definitive diagnosis. All participants will have an MRI with contrast at the end of 30 months (M30) to ensure that no cancers were missed. Participants will be asked to complete questionnaires to measure quality of life, anxiety, and their experience of MRI and ultrasound scans and data will be collected from their medical notes. The number of liver cancers detected by ultrasound will be compared to the number detected by the non-contrast MRI scans.
