An overview of Magnetic Resonance Elastography
Magnetic resonance elastography (MRE) is a medical imaging technology that combines magnetic resonance imaging (MRI) with low-frequency vibrations to create a visual map showing the stiffness of body tissues. It is primarily used to detect stiffening of the liver caused by fibrosis and inflammation in chronic liver disease. MRE is also being evaluated for potential use in diagnosing diseases in other parts of the body. The test can detect fibrosis at an earlier stage than other imaging methods and is effective for people who are obese.
What is Magnetic Resonance Elastography used for?
Magnetic resonance elastography (MRE) is a technology that combines MRI imaging with low-frequency vibrations to create a visual map (elastogram) that shows the stiffness of body tissues. It is primarily used to detect stiffening of the liver caused by fibrosis and inflammation in chronic liver disease. MRE is also being evaluated as a noninvasive way to diagnose diseases in other parts of the body. It can detect fibrosis at an earlier stage than other imaging methods and is effective in people who are obese. However, it's essential to inform your doctor about any metal or electronic devices in your body before the MRE exam, as they may pose safety hazards or affect the image quality.
How to prepare for Magnetic Resonance Elastography?
Yes, there are patient preparations needed for an MRE test. Before any MRI exam, including MRE, you will be provided with instructions to follow. In general, if you are scheduled for an MRE exam of your liver, you will likely be asked not to eat food for four hours prior to the exam, although you may drink water during that time. You should continue to take your usual medications, unless otherwise instructed. Additionally, you should remove any metal or electronic devices before the exam, as they may pose a safety hazard or affect the MRE image.
How is Magnetic Resonance Elastography conducted?
Magnetic resonance elastography (MRE) is conducted by placing a special pad against the body, over the gown, while the person is inside the MRI machine. Low-frequency vibrations are applied, which pass through the liver, and the MRI system generates images of the waves passing through the liver. The information is processed to create cross-sectional images that show the stiffness of tissue. The test is usually done as part of a conventional MRI exam.
How are Magnetic Resonance Elastography results reported?
Magnetic resonance elastography (MRE) results are reported by a doctor specially trained to interpret MRE scans, typically a radiologist. They will analyze the images from the scan and create cross-sectional images that show the stiffness of liver tissue. The doctor will discuss any important findings and next steps with the patient's doctor, who will then share the results and recommendations with the patient.
Understanding the report
Magnetic resonance elastography (MRE) results are interpreted by a doctor specially trained to interpret MRE scans, typically a radiologist. They will analyze the images from the scan and report the findings to the patient's doctor. The results provide information on the stiffness of liver tissue, which can indicate the presence and severity of fibrosis or inflammation in the liver. MRE can often detect fibrosis at an earlier stage than other imaging methods and is effective in people who are obese. The test is noninvasive and generally safer and more comfortable than a liver biopsy, which is the traditional method for testing liver fibrosis.
