Which term is described as helpful across several breast tissue evaluation scenarios such as normal tissue, ill-defined borders, and posterior margins?

• A. Fremitus
• B. Elastography
• C. Doppler
• D. Mammography

Answer: (A)

Elasticity imaging, or elastography, is the concept being tested. It adds information about tissue stiffness, which helps in several breast assessment situations. Normal tissue tends to be softer, showing low stiffness. When borders are ill-defined on standard imaging, elastography can highlight a stiffer lesion and better delineate its extent, making margins clearer. For posterior margins, stiffness mapping helps distinguish whether features seen behind or around a lesion are due to the lesion itself rather than artifacts, improving confidence about how far it extends. Since malignant tumors are typically stiffer than surrounding tissue, elastography provides a useful contrast that complements grayscale imaging and can improve characterization across these scenarios. Fremitus is a tactile vibration feature used in other chest exams, not a primary tool for breast imaging. Doppler adds vascular information but doesn’t assess tissue stiffness, and mammography shows morphology without the mechanical property information elastography provides.
