 - Transient elastography is performed using FibroScan FibroScan, Echosens with the patient lying in the dorsal decubitus position and with his right arm in maximum abduction. The tip of the transducer probe is placed in the median axillary line in the intercostal space corresponding to the right lobe of the liver. The pressure index on the screen indicates that the pressure applied with the probe is compatible with the measurement. Ten measurements per examination are necessary for good accuracy of the stiffness assessment, considering the final result expressed in kilopascals as the mean of the ten measurements. M and XL probes for obese patients are used.
