Liver Elastography, also known as Liver Stiffness Measurement (LSM), is a non-invasive test that evaluates the stiffness or elasticity of the liver. It is a specialized form of ultrasound that creates waves and measures their speed as they pass through the liver. The speed of these waves can be directly related to the stiffness of the organ; the stiffer the tissue, the faster the wave will travel.
This technique is particularly important in detecting liver conditions such as fibrosis (scarring) and cirrhosis, which result in increased liver stiffness. It helps doctors diagnose these conditions at an early stage, track their progression, and assess the effectiveness of treatments.

There is minimal preparation required for a liver elastography. You might be advised to fast for a few hours prior to the procedure to minimize gas or food in the stomach that could interfere with the test. No other specific dietary or fluid restrictions are typically required.
In the case of patients with a known allergy to ultrasound gel, it is important to inform the healthcare professional conducting the test. Moreover, it is recommended to wear loose, comfortable clothing, as you might need to expose the area around your liver for the scan.
The procedure is similar to a regular ultrasound. You will lie on your back, and a technician will apply a gel on your skin over the liver area. Then, the technician will use an ultrasound probe to send waves through your body and record how they interact with your liver.
Liver elastography is generally a painless procedure. You might feel slight pressure from the probe, but it should not cause pain.
The test itself takes about 5 to 10 minutes. However, you might be at the clinic or hospital for up to an hour, taking into account the waiting time, preparation, and discussion of results with your doctor.
Your doctor might recommend a liver elastography if they suspect you have liver disease or to monitor the progression of a known liver condition. It helps detect liver scarring, a common symptom of conditions like hepatitis and cirrhosis.
Yes, liver elastography can be used to assess how well your treatment is working by tracking changes in liver stiffness over time.
The frequency of testing depends on your individual health status and your doctor’s recommendations. If you are being treated for a liver condition, your doctor might recommend periodic testing to monitor your progress.
Liver elastography is a non-invasive and safe procedure. There is no radiation exposure and it carries minimal risks.
If your test results show increased liver stiffness, it could indicate liver scarring or another condition. You should consult with a hepatologist or gastroenterologist for further investigation and treatment options.
Liver elastography is a reliable method for assessing liver stiffness, but it may not be as accurate in individuals who are obese or have acute liver inflammation. Your doctor will interpret your results in the context of your overall health and other diagnostic tests.
While liver elastography can provide valuable information about liver stiffness and possible fibrosis, it cannot completely replace a liver biopsy in all cases. However, it may reduce the need for a biopsy in some patients.
The advent of liver elastography has provided doctors with a tool that can non-invasively monitor and detect potential liver conditions. It is a breakthrough in liver disease management, allowing for early detection and improved treatment outcomes. If you have been recommended this procedure, rest assured it's a step towards better understanding and taking care of your liver health.
