Overview

Ultrasound elastography measures liver stiffness as a surrogate for fibrosis. It reduces the need for invasive liver biopsy in many patients. Results must be interpreted in clinical context with other tests.

Techniques

Shear wave and transient elastography are common methods for liver stiffness assessment. Each technique has specific acquisition and interpretation criteria. Operator training and quality control improve reliability.

Clinical Integration

Elastography is used for screening staging and monitoring of chronic liver disease. Serial measurements track progression and response to therapy. Integration with ultrasound and laboratory data enhances decision making.

Limitations

Inflammation congestion and technical factors can affect stiffness measurements. Cutoffs vary by technique and population requiring local validation. Awareness of confounders prevents misclassification.
