MRI of the liver and hepatobiliary contrast | CION Cancer Clinics
Primovist is gadoxetate, a contrast dye made for liver MRI. Healthy liver cells absorb it, so a later set of pictures shows normal liver bright and most cancers dark. This page explains what the scan shows that a CT may miss, what happens on the day, how the dye compares with standard MRI dye, and who the scan may not suit. At CION Cancer Clinics, our team goes through your scan, blood test and biopsy reports with you and plans the next step.

The short answer
What is Primovist, and why was it chosen for my liver MRI?
Primovist is a brand name for gadoxetate, a contrast dye made for liver MRI. Unlike most dyes, healthy liver cells soak it up and pass it into the bile. That gives the radiologist an extra set of pictures, taken later, in which normal liver glows and most cancers stay dark.
How it differs from ordinary MRI dye
Standard MRI dye, like CT dye, stays in the blood and leaks into the spaces between cells. It shows how a spot takes up blood over time, in the same arterial and later phases used on CT. Gadoxetate does that too, and then adds a fourth look, called the hepatobiliary phase. Doctors call it a hepatobiliary or liver-specific contrast agent.
Why your doctor might ask for it
It is most useful when a spot is small, when a CT was unclear, or when the team needs to tell a harmless lump such as focal nodular hyperplasia apart from a cancer. It can also find extra small spots before surgery or ablation is planned. The page on why liver scans need three timings explains the earlier phases.
This page is about the scan. Whether a spot on your own scan is cancer is a question for your oncologist and radiologist together.What the pictures show
What can a liver MRI see that a CT may miss?
MRI does not use X-rays. It uses a strong magnet and radio waves, and it takes several kinds of pictures in one visit.
The timed contrast phases
Arterial, portal venous and later pictures, read the same way as on a triple-phase CT. A spot that glows early and fades later suggests hepatocellular carcinoma (HCC) in a person at risk.
The hepatobiliary phase
Taken some time after the injection, once healthy liver cells have absorbed the gadoxetate. Most HCCs and most spreads from other organs look dark against a bright liver. Focal nodular hyperplasia usually stays bright.
Diffusion pictures
These show how freely water moves in the tissue. Tightly packed tumour cells often restrict that movement, which helps pick out small spots.
Fat and iron pictures
Some sequences show fat or iron inside a nodule. This helps tell a fatty patch or an iron-laden nodule in cirrhosis from something more worrying.
Good to know
- No radiation is involved
- Repeat MRIs over years carry no radiation build-up
Not sure whether this applies to you?
Ask an oncologistOn the day
What happens during a liver MRI with Primovist?
Safety questions
You will be asked about pacemakers, metal implants, clips from old operations and metal fragments in the eyes. Tell the centre about kidney disease and any past reaction to dye.
Fasting and changing
You will usually be asked not to eat for a few hours. Jewellery, hairpins, phones and cards stay outside the room, because the magnet is always on.
Inside the scanner
You lie on a couch that slides into a tunnel. It is loud, so you get earplugs or headphones. You will be asked to hold your breath many times. Practising at home helps.
The injection and the wait
The dye goes in through a cannula in your arm. After the early pictures there is a pause, sometimes outside the scanner, before the hepatobiliary pictures are taken.
Afterwards
You can eat, drink and go home. Ask for the images on a disc or a link as well as the report, so another team can review them.
Side by side
How does Primovist compare with standard MRI dye?
Gadoxetate (Primovist)
Standard gadolinium dye
Absorbed by healthy liver cells and passed into bile
Stays in the blood and between cells, cleared by the kidneys
Adds a hepatobiliary phase that helps spot small cancers
Gives the classic timed phases only
The early arterial picture can be harder to judge
Early and late phases are usually clearer
Works less well when liver function is very poor
Not dependent on how well the liver works

Commonly believed
Is an MRI always better than a CT for the liver?
"MRI is the more expensive scan, so it must be the better one."
MRI often sees small spots more clearly, but a well-timed triple-phase CT answers the question for many people. The right scan depends on your liver, your kidneys and whether you can lie still. See CT or MRI for a liver lesion.
"A dark spot on the hepatobiliary pictures means cancer."
Many things look dark in that phase, including cysts, haemangiomas, scars and some harmless nodules. The radiologist reads it together with every other picture, never alone.
"The dye builds up in the body and harms the liver."
Gadoxetate is cleared through both the bile and the kidneys. Serious problems are rare. People with severe kidney failure need special care with any gadolinium dye, which is why the centre asks about it.
"If I am scared of closed spaces, I simply cannot have an MRI."
Many people manage with a clear explanation, music, an eye mask or a mild sedative arranged in advance. Tell the centre when booking rather than on the day.
Being straight with you
Who is this scan not right for, and what can this page not tell you?
A liver MRI is not the right first test for everyone. It may not suit people with some pacemakers or metal implants, people who cannot hold their breath or lie flat, and people with severe kidney failure. When the liver is failing badly and bilirubin is very high, the liver cells take up little gadoxetate and the special phase adds little. Standard dye or a CT may then be chosen instead.
What this page cannot tell you
It cannot read your report. The same words can mean different things depending on your liver, your hepatitis status and your earlier scans. In a person at risk, the radiologist may use the LI-RADS scoring system to grade a spot. Sometimes the answer is a short-interval repeat scan, and sometimes a biopsy.
Who can answer it
Your oncologist and the radiologist, with the images in front of them. CION arranges liver MRI through accredited diagnostic partners, and the tumour board reviews the pictures before any treatment is planned.
If your report asks for a repeat MRI, please keep that appointment. Small spots that change are the ones most worth catching early.Questions we are asked
Common questions about liver MRI and Primovist
Is Primovist the same as gadoxetate?
Yes. Gadoxetate, sometimes written gadoxetic acid or Gd-EOB-DTPA, is the medicine. Primovist and Eovist are brand names for it in different countries. Your report may use any of these words. They all describe the same liver-specific dye.
How long does a liver MRI with Primovist take?
Longer than a CT. The early pictures take a while, and then there is a pause before the hepatobiliary pictures, because healthy liver cells need time to absorb the dye. The centre will tell you how long to plan for. Bring water, your reports and someone to travel home with.
Why did I feel short of breath after the injection?
A brief feeling of breathlessness straight after gadoxetate is a known effect in some people. It passes quickly, but it can blur the early pictures. Tell the radiographer if it happened at a previous scan, so they can coach your breathing this time.
Is the dye safe if I have kidney disease?
For mild or moderate kidney problems it is usually fine. With severe kidney failure or dialysis, any gadolinium dye needs careful thought, and the centre may choose a different dye or a different scan. A recent kidney blood test helps the team decide.
Can I have it if I have diabetes or take metformin?
Usually yes. MRI dye is handled differently from CT dye, and metformin rules are often less strict. Still tell the centre about every tablet you take, and do not stop any medicine unless the doctor who ordered the scan tells you to.
Can it be done while breastfeeding?
Usually yes. Only a tiny amount of dye passes into breast milk. Some mothers choose to express and store milk beforehand, or to pause briefly afterwards. Ask the radiologist or your doctor, who can talk you through what the centre advises.
My MRI and CT disagree. Which one is right?
Neither is automatically right. Different scans see different things, and a spot can also change between scans. This is exactly the kind of question a tumour board or a second opinion on imaging is for. Bring both sets of images.
Can CION arrange a liver MRI for me?
Yes. CION arranges liver MRI, with standard or liver-specific dye, through accredited diagnostic partners. Your oncologist decides which dye suits your liver and kidneys. If you already have scans, bring the images so they can be reviewed before anything is repeated.
