Overview

Elastography assesses tissue stiffness as a biomarker for fibrosis tumors and focal lesions using shear wave or strain techniques.

Technique

Ultrasound shear wave and MR elastography use different physics but both produce stiffness maps for clinical interpretation.

Clinical Uses

Liver fibrosis staging breast and thyroid lesion characterization and musculoskeletal tendon assessment.

Limitations and Safety

Operator dependence for ultrasound and motion sensitivity for MR. Standardization improves reproducibility.
