MRI Elastography: What You Need To Know

Purpose and Preparation for MRE Exam

The MRE exam, or Magnetic Resonance Elastography, is a non-invasive medical test that measures the stiffness of the liver. This measurement aids in the diagnosis of liver diseases such as fibrosis and cirrhosis.

Preparation for an MRE involves:

  • Fasting for 4 hours prior to the exam to prevent stomach content from interfering with the imaging of the liver.
  • It is also recommended to wear comfortable clothes that do not contain metal parts, as these can interfere with the magnetic fields used during the procedure.

It is important for individuals to be aware of their health conditions or medications, as certain situations may impact the safety or effectiveness of MRE testing. Such situations include:

The MRE exam serves to evaluate liver health, with preparation including fasting and attire considerations, ensuring the test's effectiveness.

What to Expect and Risks of MRI Elastography

MRI Elastography is a non-invasive imaging test that measures the stiffness of organs, primarily focusing on the liver. This technique is used in the diagnosis and monitoring of diseases such as fibrosis (scarring) or cirrhosis. The process involves the patient lying on their back inside an MRI machine for approximately 20 to 30 minutes.

Before the scan, all metal objects must be removed from the patient's body. These include:

  • Jewelry
  • Devices like hearing aids or pacemakers, which can interfere with the magnetic field.

There are few risks associated with MRI Elastography. It may cause discomfort due to the necessity of lying still in a confined space for an extended period. Claustrophobic individuals may experience discomfort, and options to alleviate this discomfort can include sedation or the use of open MRI machines.

Additionally, there is a possibility of allergic reactions to contrast agents used during the procedure, although these cases are rare. There is also a slight chance that the high-frequency vibrations used during elastography could slightly heat tissues, but this is also unlikely.

MRI Elastography is considered safe and painless when conducted by skilled professionals.

Liver Fibrosis Diagnosis and Advantages of MRI Elastography

Liver fibrosis diagnosis is critical for identifying the thickening and scarring of tissues in the liver. MRI Elastography is an advanced method used for this purpose.

Fibrotic livers exhibit greater stiffness compared to healthy ones, and MRI elastography measures this stiffness by utilizing magnetic waves to create a visual map of the liver's elasticity or firmness.

The procedure offers several advantages:

  • Non-invasive: It does not require needles or surgical incisions.
  • Accurate: It is effective in detecting various stages of fibrosis.
  • Safe: It involves minimal risks.

In conclusion, MRI elastography provides precise results while being non-invasive and safe, establishing it as a valuable tool for liver fibrosis diagnosis.
