SWE = shear wave elastography
SWS = shear wave speed

SWI = ? (встречается в тексте 1 раз, я подозреваю, что это просто опечатка, и должно быть тоже SWE, но, возможно, это просто неизвестный мне термин)


Based on a recent large multi-center study (BE1) using 2D SWE, a cut-off value of 80 kPa (5.2 m/s) was determined to distinguish BI-RADS category 3 and BI-RADS category 4a lesions with better specificity (Berg, Cosgrove et al. 2012). Examples are presented in
Figure 7. Tissue measurements in an ROI can be displayed in speed (m/s) or in pressure/elasticity (kPa). The measurement of stiffness should be obtained from the area of highest stiffness within the lesion or the surrounding tissue. This large multi-center trial demon-
strated that when SWS is added to BIRADS classification in B-mode imaging diagnostic accuracy increases (Berg, Cosgrove et al. 2012). The evaluation of SWE signal homogeneity and lesion to fat ratios were the best differentiators of benign and malignant. The addition of SWE increased the characterization of lesion over BI-RADS alone, with a sensitivity and specificity of 93.1% and 59.4% for BI-RADS and 92.1% and 76.4% with the addition of SWE. The authors note that the major value of the addition of SWE is in BI-RADS 3 and 4a lesions where the **SWI** results are used to upgrade or downgrade the lesion (Berg, Cosgrove et al. 2012, Schaefer 2013). The same study included an analysis of reproducibility, which was very high (Cosgrove, Berg et al. 2012).
