Breast (Elastography)

Breast — Elastography

What is elastography? (strain vs shear-wave) Basic physics & interpretation concepts

Strain elastography — technique & visual scoring Shear-wave elastography — quantitative measures (kPa, m/s)

Presets, probe selection & calibration checks Quality metrics (stability maps, rejection criteria)

ROI selection: lesion ROI, background, reference tissue Avoiding compression artefact & precompression errors

Strain score systems (1–5): examples Shear-wave thresholds (kPa/m/s) & suggested cutoffs

How elastography modifies suspicion (BI-RADS adjunct) Discordant cases & when to biopsy despite soft elastography

Benign examples: cystic lesions, fibroadenoma patterns Malignant stiffness patterns & heterogeneity

Precompression, edge-effects, depth & motion artefacts Practical fixes & scan repeats

What to include: elastography maps, numbers, QC status Suggested phrasing for reports

When elastography can influence biopsy decisions Sampling tips when stiff area vs soft rim present

Key studies & meta-analyses Limitations of current evidence
