FibroScan® procedure for users

Find the key recommendations to run a liver examination with FibroScan®


Pre examination requirements

Patient shall be fasting for at least 3 hours-however, they can drink water prior to their scan.1,2,3 

Patient shall be lying on the examination bed for 5 minutes before the examination for the body to rest.

Operator shall be duly trained and certified by Echosens or its local representative. 

Device probes shall be calibrated.

Examination room set-up


  • Facing screen
  • On a height adjustable stool 



  • Lying flat on the examination bed
  • Right arm under the head
  • Banana shaped position 

Probe selection criteria

Ensure that the probe used corresponds to the patient’s body type:

  • Probe selection criteria are based on thoracic perimeter (TP)
  • To chose between the M of XL probe, follow the automatic probe selection tool displayed in real time.


Warning: Selecting XL Probe only when M probe examination fails is not correct. Follow the automated probe advice.

Examination reliability criteria


  • At least 10 measurements at the same spot shall be performed with one single probe.
  • No recommendations on IQR.

No, FibroScan® can be performed on every single patient. Examinations on pregnant women and patients with active implantable medical devices (pacemaker, defibrillator…) are not contraindicated.

Contraindications have been lifted since April 2016 in Europe, and subsequently in all other countries (including the United States since March 2023), except in Japan.

Probes are calibrated by Echosens support. All you need to know about probe calibration is available in the calibration FAQ.

The Interpretation Guide and cut-offs are on myFibroScan (app and website).

Peer-reviewed articles used for the cut-off are available in our Clinical Library.

Training and certification by Echosens or its local representatives is prerequisite for every FibroScan® user.

Connect with your local representative or contact us directly through the contact page available on this website.

There are many clinical studies available for reference in our clinical library.

– For methotrexate, filter your search by selecting Etiology = “Drug induced liver injury (DILI)”.

– For primary biliary cirrhosis and primary sclerosing cholangitis, filter your search by selecting Etiology = “Cholestatic disease”.

– For haemochromatosis, filter your search by selecting aetiology = “Other”.

The FibroScan® Family of Products (models: Compact 530, Mini+ 430 and Expert 630) is intended to provide 50Hz shear wave speed measurements and estimates of tissue stiffness as well as 3.5 MHz ultrasound coefficient of attenuation (CAP™: Controlled Attenuation Parameter) in internal structures of the body. The shear wave speed and stiffness, and CAP™ may be used as an aid to diagnosis and monitoring of adult patients with liver disease, as part of an overall assessment of the liver. Shear wave speed and stiffness may be used as an aid to clinical management of pediatric patients with liver disease. The FibroScan®  630 (Expert) is also indicated for noninvasive measurement in the spleen of 100 Hz shear wave speed and estimates of stiffness that may be used as an aid to diagnosis, monitoring and clinical management of adult patients with liver disease, as part of an overall assessment of the liver.
