Figure 4.

A 50-year-old premenopausal woman with a pathologically proven DCIS. The gray scale ultrasound feature showed a 0.87 cm, ill-defined, oval hypoechoic mass which was assessed as BI-RADS category 4B. After applying a color overlay, SWE showed a homogeneous blue color overlaying the mass. The quantitative SWE measurements were 10.3 kPa for the mean elasticity, 11.7 kPa for the maximum elasticity, and 2.35 for the elasticity ratio, all of which were below the corresponding cutoff values. SWE, shear wave elastography.
