Breast Elastography: Present and Future
Gradually, ultrasound equipment have suffered a major technological development, starting with the Doppler log or the introduction of harmonics, until the recent use of intravenous contrast and of course elastography. The first team was launched in 2003, later emerging numerous similar systems have been launched different commercial houses, which have been incorporated to ultrasound equipment p...
متن کاملAnalytic modeling of breast elastography.
The elastic moduli of tumors change during their pathological evolution. Elastographic imaging has potential for detecting and characterizing cancers by mapping the stiffness distribution in tissues. In this paper a micromechanics-based analytical method was developed to detect the location, size, and elastic modulus of a tumor mass embedded in a symmetric two-dimensional breast tissue. A close...
متن کاملCompression Effects in Breast MR Elastography
on fat-saturated T2-weighted images. Arrow shows the location of the compression on the tested breast. The other breast was not compressed. In the tested breast, glandular tissue stiffness = 0.74 ± 0.13 kPa (prior-compression) vs. 0.95 ± 0.13 kPa (20% compression). Fig.1. Breast MRE compression setup. (1) magnet bore, (2) subject, (3) RF coil, (4) driver, (5) bed, (6) biopsy plates, (7) adjusta...
