Liver MRI Scan: Complete Guide

A liver MRI scan is the most sensitive imaging technique for evaluating the liver, providing detailed views of liver tissue, blood vessels, bile ducts, and surrounding organs. Whether you are investigating abnormal liver blood tests, a lesion found on ultrasound, or monitoring a chronic liver condition, MRI offers unmatched diagnostic clarity. Lola Health provides access to private liver MRI scans at over 150 UK centres.

What a Liver MRI Scan Shows

• Liver lesions and tumours — characterisation of benign lesions (haemangiomas, focal nodular hyperplasia, adenomas) versus malignant tumours (hepatocellular carcinoma, cholangiocarcinoma, metastases).
• Fatty liver disease (steatosis) — quantification of fat content within the liver using specialised MRI sequences.
• Liver fibrosis and cirrhosis — assessment of liver scarring and structural changes. MR elastography can measure liver stiffness.
• Iron overload (haemochromatosis) — T2* sequences can quantify iron deposition in liver tissue.
• Bile duct abnormalities — MRCP (magnetic resonance cholangiopancreatography) can visualise the biliary tree and detect stones, strictures, or tumours.
• Vascular abnormalities — portal vein thrombosis, Budd-Chiari syndrome, and hepatic vein abnormalities.
• Liver abscesses — collections of infection within the liver.
• Liver cysts — simple cysts or complex cystic lesions that require characterisation.

When You Might Need a Liver MRI Scan

• Abnormal liver function blood tests requiring further investigation
• A lesion or mass found on ultrasound that needs characterisation
• Monitoring of known liver disease (cirrhosis, hepatitis, fatty liver)
• Screening for liver cancer in high-risk individuals
• Suspected haemochromatosis or iron overload
• Abdominal pain localised to the right upper quadrant
• Jaundice or unexplained itching
• Assessment before liver surgery or transplantation
• Surveillance of known liver lesions

How to Prepare

• Fasting: You will typically be asked to fast for 4 to 6 hours before a liver MRI to reduce bowel motion artefact and improve image quality.
• Metal check: Standard MRI safety screening.
• Medications: Continue usual medications unless advised otherwise.
• Previous imaging: Bring previous ultrasound or CT reports if available.

What to Expect During the Scan

1. Positioning: Lie on your back with a body coil placed over your abdomen.
2. Breath-holds: You will be asked to hold your breath for short periods (15 to 20 seconds) at intervals to reduce motion blur.
3. Duration: 30 to 50 minutes depending on the protocol.
4. Contrast: Liver-specific contrast agents (such as gadoxetate/Primovist) are commonly used and are particularly helpful for lesion characterisation.
5. After: Resume eating and normal activities after the scan.

How Much Does a Liver MRI Scan Cost?

Private liver MRI scans in the UK typically cost between £400 and £900. Lola Health provides transparent pricing with expert radiologist reporting at over 150 UK centres.

Liver MRI and Blood Testing

Liver blood tests are one of the most important complements to liver MRI:

• Liver function tests (ALT, AST, ALP, GGT, bilirubin, albumin): Abnormal results are often the reason a liver MRI is requested. These tests measure liver enzyme activity and function, helping identify inflammation, obstruction, or damage.
• Full blood count: Low platelets or abnormal white cells may indicate liver disease or portal hypertension.
• Ferritin and transferrin saturation: Essential for diagnosing haemochromatosis. Elevated ferritin with high transferrin saturation warrants liver MRI for iron quantification.
• Hepatitis B and C serology: Chronic viral hepatitis is a major cause of liver disease and liver cancer. Positive serology with abnormal liver tests often leads to MRI surveillance.
• AFP (alpha-fetoprotein): A tumour marker that may be elevated in hepatocellular carcinoma. Used alongside MRI for liver cancer screening.
• HbA1c: Non-alcoholic fatty liver disease (NAFLD) is strongly associated with type 2 diabetes and metabolic syndrome.
• Lipid profile: Dyslipidaemia often accompanies fatty liver disease.

Start with a Lola Health blood test to check your ALT, AST, GGT, bilirubin, albumin, and iron studies. If results suggest further investigation, a liver MRI can provide the structural detail your blood results can't show. Peak Insights 70 covers these markers across 70 biomarkers.

Frequently Asked Questions

Can a liver MRI detect fatty liver?

Yes. Specialised MRI sequences can quantify the percentage of fat in the liver, making it more accurate than ultrasound for diagnosing and grading fatty liver disease.

Is the scan painful?

No. The scan is completely painless. You may feel a brief cool sensation when contrast is injected.

Do I need a referral?

No. Book directly through Lola Health.

Why do I need to fast?

Fasting reduces bowel gas and motion, improving image quality. It also optimises contrast agent uptake by the liver.

How accurate is liver MRI for detecting tumours?

Liver MRI with contrast is the most accurate non-invasive method for characterising liver lesions. It can distinguish benign from malignant lesions in the majority of cases.

Can liver MRI measure iron levels?

Yes. T2* MRI sequences can accurately quantify iron concentration in liver tissue, which is invaluable for managing haemochromatosis.

What is MRCP?

MRCP (magnetic resonance cholangiopancreatography) is a specialised MRI technique that visualises the bile ducts and pancreatic duct without contrast injection. It is often performed alongside a liver MRI.
