Recommendations criteria for a reliable stiffness examination liver stiffness result ≤ 7,1kPa a minimum of 10 valid measurements YES NO performed at the same spot in the right lobe of the liver an iQR/Median ratio ≤30% only if reliABle iQr/mediAn ≤ 30% stiffness final result is >7,1 kPa n.b : Success rate is not a relevant reliability criteria for YES NO liver stiffness measurement examination. reliABle unreliABle Stiffness reliability criteria algorithm taking into account both stiffness final Median result(kpa) and IQr/Median stiffness ratio(%) [2]. recent publications focusing on criteria for a reliable stiffness examination exhibited the following results: • On a 254 hcV infected patients cohort [1]: → Success rate has no impact on accuracy of LSM. • On a 1165 patients cohort of patients with chronic liver disease [2]: → usual definition for LSM reliability is not relevant; →LSM success rate criteria was not relevant for clinical practice and clinical research; →LSM result must be interpreted according to both IQr/Median (%) and liver stiffness level (kpa). bibliography: 1.
