 Advantages and limitations of imaging techniques.

TechniqueAdvantagesLimitations
TEWidely validated; bedside; AUROC > 0.9 for cirrhosisDedicated device; less accurate in obesity/ascites; false positives
pSWEStandard US; operator selects ROI; high applicabilityNarrow range; quality criteria not fully defined
2D-SWEReal-time; adjustable ROI; wide stiffness rangeLearning curve; inflammation may influence
MREWhole-liver assessment; high accuracy; obesity/ascites feasibleExpensive; MRI required; iron overload limits

TE: transient elastography; pSWE: point shear wave elastography; 2D-SWE: two-dimensional shear wave elastography; ROI: region of interest; MRE: magnetic resonance elastography; MRI: magnetic resonance imaging.
