What is this test?

Liver MRI with intravenous contrast is an imaging test that uses magnetic fields and a contrast medicine injected into a vein to create detailed pictures of the liver. It can show the liver's structure, blood flow, bile ducts, and surrounding tissues.

Why might I need this test?

A clinician may order this scan to investigate an abnormal liver test, evaluate a liver mass, or look for problems such as inflammation, fibrosis, infection, cirrhosis, or bile duct disease. It may also help clarify findings seen on an ultrasound or CT scan.

How is the test performed?

You will lie on a padded table that moves into an MRI scanner. The scan usually takes about 20 to 45 minutes, although timing varies. Contrast is given through an intravenous line, and the imaging team may ask you to hold your breath briefly at certain times.

How do I prepare for the test?

Tell the imaging team about any metal in your body, implanted devices, pregnancy possibility, kidney disease, or previous reaction to MRI contrast. Follow the facility's instructions about eating, drinking, and taking medicines; you may be asked to avoid food for several hours if sedation is planned.

Frequently asked questions

Is a liver MRI with contrast the same as a liver biopsy?
No. MRI is a noninvasive imaging test, while a biopsy removes a small piece of liver tissue for examination. A biopsy may still be needed if imaging and other results do not provide a clear answer.
Will I feel the contrast injection?
The injection may cause a brief cool or warm sensation, and the IV site can feel sore afterward. Serious reactions are uncommon, but tell the staff immediately about significant discomfort, dizziness, itching, or trouble breathing.
Can I have this test if I have a metal implant?
Many MRI-compatible implants are safe, but some are not. Provide the name and model of every implant or device to the imaging team before the scan so they can confirm safety.
