FibroScan

About This Test

FibroScan is a non-invasive liver scan that uses ultrasound technology to accurately rule out or determine the presence of liver disease. By delivering a pulse into the liver, FibroScan measures its stiffness, indicating whether a patient has significant scarring. If there is evidence of liver scarring, the patient may require further testing to detect or monitor conditions such as fatty liver disease, fibrosis, or cirrhosis. 

Our gastroenterology (GI) doctors review FibroScan results and relay interpretations to patients directly, working to answer any questions and/or concerns in the process. 

What is the difference between fatty liver and liver stiffness?

Fatty liver, also known as steatosis, may progress to liver stiffness (fibrosis or cirrhosis) if left untreated. The accumulation of fat cells in the liver contributes to significant scarring; FibroScan offers early detection to manage and monitor the progression of these liver conditions. 

Who is a good candidate for FibroScan?

Anyone can benefit from FibroScan's early detection, but it may be ideal for patients with diabetes, high cholesterol or working toward weight loss, as they tend to be more at risk for liver disease. Receiving more than one FibroScan is helpful in tracking the results of focused lifestyle changes. For patients living with liver disease, FibroScan is also beneficial in assessing where they are in the treatment process. 

What does FibroScan entail?

FibroScan is a simple test administered by a nurse. The patient is instructed to lie down and stretch the right side of the body with the arm extended overhead. A small portion of ultrasound jelly is then placed between the ribs before the device is triggered, delivering 10 pulses. The results are then averaged together, and further calculations are completed for interpretation and review by a GI doctor. The scan lasts approximately 5 to 10 minutes and results are often returned within a couple of weeks. 

Understanding my FibroScan results

FibroScan results include both a kilopascals (kPa) and controlled attenuation parameter (CAP) score. The kPa score indicates the stiffness, or degree of scarring, in the liver and the CAP score indicates fat density. When the machine delivers a sound pulse, the time it takes to bounce back determines the kPa score; the time it takes to absorb the sound determines the CAP score. A higher kPa score means more scarring, while a higher CAP score means more fat density.  In both instances, the higher the score, the greater the risk of liver disease or damage. 

How accurate is the FibroScan?

FibroScan is incredibly accurate at ruling out liver disease or determining when a patient has significant fibrosis. It's an invaluable tool in identifying at-risk patients and serving as a guidepost for patient progress. 

How can I schedule a FibroScan?

Any doctor can order a FibroScan, but a GI may be consulted if there is significant damage or further cause for concern. Speak with your primary care physician to discuss further or assess general liver health.
