FibroScan (Liver Elastography)

FibroScan (Liver Elastography) is a painless, non-invasive scan that measures how stiff the liver is, which tells doctors how much scarring (fibrosis) has built up inside it.

During the scan, a small probe placed on the skin sends a gentle vibration into the liver. The machine tracks how fast that vibration travels through liver tissue. Stiffer tissue — the kind damaged by long-term disease — lets the vibration move faster. The machine converts this speed into a stiffness score, giving the doctor a picture of liver health without needing to cut or take a tissue sample.

FibroScan is used whenever a doctor needs to assess the degree of liver damage or monitor how the liver is responding to treatment. It is particularly useful as an alternative — or addition — to a liver biopsy (a procedure where a needle removes a small piece of liver tissue for examination).

• Chronic hepatitis B or C (long-term viral liver infections)
• Non-alcoholic fatty liver disease (NAFLD) — fat build-up in the liver unrelated to alcohol
• Non-alcoholic steatohepatitis (NASH) — a more severe form of fatty liver with inflammation
• Alcoholic liver disease — liver damage caused by long-term heavy alcohol use
• Autoimmune hepatitis — when the body's immune system mistakenly attacks the liver
• Primary biliary cholangitis and primary sclerosing cholangitis — conditions that damage the bile ducts (the tubes that carry digestive fluid from the liver)
• Monitoring a known diagnosis of liver fibrosis or cirrhosis (advanced scarring) over time
• Assessing liver health before starting medications that can affect the liver

FibroScan may not give reliable results in certain situations. Your doctor will usually choose a different approach if any of the following apply.

• Significant amounts of fluid in the abdomen (ascites), which interferes with the vibration signal
• Very high body weight, as the probe may not reach the liver through a thick layer of tissue
• Pregnancy, as a precaution
• A cardiac pacemaker (a device implanted to regulate heartbeat) — the vibration feature used in some FibroScan models may be unsuitable
• Active inflammation or acute liver injury, which can falsely elevate the stiffness reading

FibroScan is a non-invasive diagnostic test that does not use needles, radiation, or cuts, and it is considered very safe for the vast majority of patients. Serious risks are not associated with this procedure.

• Mild discomfort or pressure where the probe touches the skin — this fades immediately after the scan
• Technically inadequate results (when the machine cannot get a reliable reading), which may mean the scan needs to be repeated or a different test used
• Falsely elevated stiffness scores if the patient has recently eaten, has active liver inflammation, or has heart failure (fluid congestion that stiffens the liver independently of scarring) — your doctor will take these factors into account when interpreting results

Preparation for FibroScan is straightforward and does not involve complex medical steps, but following the instructions carefully helps the machine produce an accurate reading.

Most hospitals ask patients to fast (eat and drink nothing except water) for at least two hours before the scan, because a meal can temporarily increase liver stiffness and skew the result. Some centres extend this to four hours, especially if the patient has a condition like NASH or metabolic disease. Your referring doctor or the scanning centre will give specific instructions. There is usually no need to stop regular medications, but you should inform the team of everything you are taking. Alcohol should be avoided on the day of the scan, as it can also affect stiffness readings.

No special blood tests are required purely to perform FibroScan, but your doctor will often review recent liver blood tests (such as liver enzyme levels and a full blood count) alongside the scan result to build a complete picture. In some cases, an ultrasound (USG) of the abdomen may be done at the same visit.

The scan itself follows a series of simple steps.

• You lie on your back on an examination table with your right arm raised behind your head to expose the right side of your ribcage.
• A small amount of water-based gel is applied to the skin over the lower right chest and upper abdomen — the area closest to the liver.
• The technician places the probe gently against the skin and applies light pressure.
• The probe sends a brief, gentle vibration into the body. Most people feel nothing or only a very mild tapping sensation.
• The machine takes multiple measurements — usually around ten — in quick succession, and keeps only the readings that meet its quality criteria.
• The technician reviews the accepted measurements on screen. The whole process typically takes between five and fifteen minutes, though this can vary.
• Results are usually available immediately and are passed to your doctor for interpretation.

Because FibroScan does not involve any cuts, needles, or sedation (medication that makes you drowsy), there is virtually no recovery period. Patients can eat, drink, and return to normal daily activities immediately after the scan.

• You may eat and drink normally as soon as the scan is finished.
• There are no restrictions on driving, physical activity, or returning to work.
• No wound care is needed — the gel is simply wiped off the skin.
• Your doctor will usually schedule a follow-up consultation to explain your results in full, discuss what the stiffness score means for your specific condition, and decide whether further tests or treatment adjustments are needed.
• If FibroScan is being used to monitor a known liver condition, your doctor will advise how often repeat scans are recommended — this varies depending on the underlying disease and how it is being managed.
• Lifestyle measures that support liver health — such as limiting alcohol, maintaining a healthy weight, and managing conditions like diabetes — are often discussed at the follow-up appointment, as these can influence future FibroScan readings.
