MRI Liver Fat Quantification, also known as MRI Proton Density Fat Fraction (PDFF), is an advanced imaging technique used to accurately measure the amount of fat in the liver. This non-invasive test is especially beneficial in detecting and quantifying fatty liver disease, a condition that occurs when too much fat is stored in liver cells.
Excessive fat in the liver can lead to inflammation, scarring (fibrosis), and eventually severe liver damage such as cirrhosis. Timely and accurate detection of fatty liver disease can facilitate early intervention, potentially preventing disease progression and promoting healthier liver function.

MRI Liver Fat Quantification, also known as MRI Proton Density Fat Fraction (PDFF), is a non-invasive imaging technique that measures the amount of fat in the liver. It is especially useful in detecting and monitoring fatty liver disease.
This test is performed if your doctor suspects you have fatty liver disease, a condition characterized by excessive fat stored in liver cells. It can help to diagnose the condition, evaluate its severity, monitor its progression, and assess the response to treatment.
You'll be asked to lie on a sliding table that moves into the circular opening of the MRI machine. The machine generates a magnetic field and radio waves to create detailed images of your liver. The test is painless and typically takes between 30 to 60 minutes.
You may be asked to fast for a few hours before the test to ensure that the liver is in a consistent metabolic state for accurate measurement of fat content.
High liver fat content may indicate the presence of fatty liver disease. Depending on the extent of fat accumulation, you may be diagnosed with non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH), a more severe form of the disease. This condition can lead to serious liver damage if not managed properly.
A radiologist will review the images from the MRI and provide a detailed report to your doctor. This typically takes a few days. Your doctor will then discuss the results with you and determine the next steps based on the findings.
No, MRI uses a magnetic field and radio waves, not radiation, to create detailed images of the body.
If you're pregnant or suspect you may be, it's important to inform your doctor, as an MRI scan could potentially pose a risk to the developing fetus.
If you have claustrophobia, you should inform your doctor, who might prescribe medication to help you relax during the scan. In some cases, an open MRI machine may be available which can be less stressful for patients with claustrophobia.
If your results show a high level of fat in your liver, it could indicate fatty liver disease. Your doctor will consider these results along with your other symptoms, medical history, and any other tests to determine the best course of action for diagnosis and treatment.
MRI Liver Fat Quantification is a valuable tool for diagnosing and managing fatty liver disease. By measuring the amount of fat in the liver, it provides vital information that helps doctors make informed decisions about your treatment plan. If you have any concerns about the test, you should discuss them with your doctor to ensure you understand why the test is being done and what the results mean.
