Fibroscan® practice improvement with a real-time assistance ultrasound tool: a premiminary study

Vibration-controlled transient elastography (VCTE^¿) based on the Fibroscan^® device (Echosens, Paris, France) is used to assess non invasively liver stiffness which is correlated to hepatic fibrosis. Currently, operators need to be trained to conduct successful examinations with the Fibroscan^®. The liver is visually localized via TM and Ascan modes. Furthermore, the use of an ultrasound scanner is recommended to localize the liver on obese patients, and to identify the optimal measurement window. To facilitate the examination, we propose in this paper new indicators derived from the ultrasound signal to enable automated liver localization.
