Elastography

Overview

Elastography measures tissue stiffness using ultrasound or MRI based methods. It aids in differentiating benign from malignant lesions. It provides quantitative metrics that complement conventional imaging.

Liver Fibrosis

Elastography is widely used to stage liver fibrosis non invasively. It reduces the need for liver biopsy in many patients. Serial measurements monitor disease progression and treatment response.

Breast and Thyroid

Elastography improves characterization of breast and thyroid nodules. Stiffness metrics add diagnostic information to ultrasound imaging. It supports biopsy decision making and follow up.

Technical Considerations

Operator technique and equipment affect elastography results. Standardization and quality control improve reproducibility. Interpretation should be integrated with clinical and imaging context.

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.
