FibroScan examination will be performed to assess liver stiffness according to the manufacturer's recommendation and in accordance with the device's FDA clearance. The device is equipped with two probes (M and XL) dedicated to different morphology and operating at different measurement depths. The M probe operates between 25 and 65 mm below the skin surface and the XL probe operates between 35 and 75 mm. The device's software automatically recommends which probe is the most appropriate during examination based on the real time assessment of the skin to liver capsule distance (automatic probe selection tool). The FibroScan used in this study will be equipped with a software allowing, in addition to liver stiffness, measurement of the Controlled Attenuation Parameter (CAP) which is related to liver steatosis with different algorithm. This additional software feature is FDA approved. Operators will be trained and certified by the manufacturer or its local representative. Recommendation from the Automatic Probe Selection tool will be followed. At least ten valid measurements should be obtained. De-identified acquisition files will be reviewed by the device's manufacturer (Echosens) to confirm the operator's choice of measurement depths and eventually change them as well as analyze the additional ultrasonic signals.
