Breast elastography is a specialized, non-invasive ultrasound technique used to assess the stiffness (elasticity) of breast tissue, particularly in findings such as nodules or masses.
The technique is based on the principle that benign lesions tend to be softer, while malignant ones are typically harder. It provides a “stiffness map” (elastogram), either color-coded (qualitative) or numerical (quantitative), aiding in the more accurate evaluation of suspicious lesions. It is used as a complementary tool alongside standard breast ultrasound to improve diagnostic accuracy and reduce unnecessary biopsies.
Applications of breast elastography:
- Differentiation between benign, suspicious, or malignant lesions
- Evaluation of breast nodules detected on ultrasound
- Reduction of unnecessary fine needle aspiration (FNA) or core biopsies
- Monitoring of known nodules or tumors over time
Procedure
The examination is performed in conjunction with a standard breast ultrasound. The doctor places the ultrasound probe on the breast and applies either manual pressure (strain elastography) or uses shear wave technology. The tissue’s resistance to deformation is measured and displayed on the screen. The examination is painless, radiation-free, and lasts only a few minutes.
