Fremitus is also known as ?

• A. Vibrational Doppler Imaging (VDI).
• B. Color Doppler.
• C. Strain imaging.
• D. Power Doppler.

Answer: (A)

Fremitus in this context is the vibration of breast tissue that can be visualized using Doppler-based technique. When tissue is gently vibrated, the resulting tiny motions create Doppler shifts that can be mapped to show how the tissue moves—this is Vibrational Doppler Imaging. It specifically captures tissue motion due to external vibration, producing a fremitus image of the breast. Color Doppler, by contrast, shows blood flow velocity within vessels, not mechanical vibration of surrounding tissue. Strain imaging (elastography) measures how tissue deforms under compression to assess stiffness, rather than its vibration pattern. Power Doppler emphasizes the presence and strength of Doppler signals without directional information, and again does not depict tissue vibration patterns.
