Liver elastography in patients scheduled for bariatric surgery.
Red lines indicate recommend cut-offs for detections of advanced liver fibrosis (TE) [13] and liver cirrhosis (acoustic radiation force impulse imaging, ARFI) [8]. Application of these cut-offs in patients scheduled for bariatric surgery results in overestimation of fibrosis severity in a high percentage of cases.

The diagnostic accuracy of the ELF score for detection of advanced liver fibrosis (≥F2) was evaluated in a cohort of non-bariatric NAFLD patients [17]. The calculated cut-off was applied to the bariatric cohort and correctly classified the majority of patients. Grey boxes below each bar indicate the median value.
