Shear wave versus strain elastography of breast lesions-The value of incorporating boundary tissue assessment.

Purpose: This prospective study compares the diagnostic performance of strain elastography (SE) based on the elastogram to B-mode (E/B) size ratio to shear-wave elastography (SWE) incorporating assessment of boundary tissue stiffness.

Methods: In this prospective study, 81 women consented to undergo ultrasound (US) elastographic assessment prior to biopsy of their mass(es). A total of 101 masses were evaluated with SE and SWE using a single machine (Siemens Acuson S2000).
