What are three dynamic techniques we use in breast sonography?

• A. Compression
• B. Echo palpitation
• C. Fremitus
• D. Compression, echo palpitation, fremitus

Answer: (D)

In breast ultrasound, dynamic maneuvers are real-time ways to test how tissues respond to movement, pressure, and vibration, giving information beyond static images. Compression involves gently squeezing the tissue with the probe to see how easily structures deform; cysts typically compress and flatten, while solid masses may resist change, helping assess consistency and margins. Echo palpation is a controlled probing sensation with the transducer that evaluates tissue elasticity by observing how different areas deform under pressure, which can help distinguish softer, benign tissue from firmer, potentially suspicious lesions. Fremitus uses a small amount of vibration through the breast to observe how the tissue transmits motion, providing another dimension to compare lesion stiffness and border definition. Together, these three dynamic techniques give a fuller picture of a lesion’s behavior in real time, aiding characterization beyond what static imaging alone can show.
