What Is FibroScan and Do You Need One?
If you've been told you have fatty liver disease, elevated liver enzymes, or chronic hepatitis — or if your doctor has recommended a 'liver scan' — you may have heard the term FibroScan. It's a test that has genuinely changed how we evaluate liver disease, offering a window into liver health that previously required a needle biopsy.
Here's what FibroScan is, what it tells us, and whether you might benefit from one.
What Is FibroScan?
FibroScan is a brand name for a device that uses transient elastography — a form of ultrasound technology — to measure the physical properties of the liver. Specifically, it measures two things: liver stiffness (a marker of fibrosis, or scarring) and liver fat content (the controlled attenuation parameter, or CAP score).
The procedure is simple. You lie on your back and a technician places a probe on the skin over the right side of your abdomen. A small painless vibration is transmitted through the skin into the liver, and the device measures how quickly it travels — stiffer, more scarred liver tissue transmits the vibration faster. The test takes about 10 minutes, requires no needles, no sedation, and causes no discomfort. Results are available immediately.
What Can FibroScan Detect?
FibroScan provides a liver stiffness measurement in kilopascals (kPa) and a CAP score in decibels per meter (dB/m). These measurements are interpreted in the clinical context of your history, blood tests, and risk factors:
Normal stiffness + low CAP: No significant fibrosis or steatosis — reassuring
Elevated CAP with normal stiffness: Significant liver fat (steatosis) without advanced fibrosis — early NAFLD
Elevated stiffness: Suggests fibrosis; higher values suggest more advanced fibrosis or cirrhosis
FibroScan is most accurate for detecting significant fibrosis (F2 and above) and cirrhosis. It is less reliable for distinguishing mild fibrosis (F1) from normal.
Who Should Have a FibroScan?
We use FibroScan for patients with:
Known or suspected NAFLD — to assess the degree of liver fat and fibrosis
Chronic hepatitis B or C — to monitor fibrosis progression and inform treatment decisions
Alcohol-related liver disease — to assess severity
Abnormal liver enzymes of uncertain cause
Monitoring response to treatment for fatty liver disease (such as our NAFLD program)
FibroScan vs. Liver Biopsy
Liver biopsy has historically been the gold standard for staging liver fibrosis. But biopsy is invasive — it requires a needle passed through the skin into the liver, carries a small but real risk of bleeding, and samples only a tiny portion of the organ (which can lead to sampling error). FibroScan is non-invasive, assesses a much larger area of the liver, and has been validated against biopsy in thousands of patients. In most cases of chronic liver disease, FibroScan allows us to make confident management decisions without biopsy.
Is FibroScan Available at AGG?
Yes. FibroScan is available at Advanced Gastroenterology Group as part of our comprehensive liver disease evaluation and NAFLD program. If your primary care physician has referred you for liver evaluation, or if you have risk factors for fatty liver disease, ask us whether FibroScan is appropriate for you.
