Figure 1. Malignant elastography images with color-filling defect (invasive carcinoma, nonspecific type (IC, NST) Grade 2).
(A) Qualitative elastography shows low stiffness with a predominantly green color map and a large area of color-filling defects (arrow); (B) Quantitative elastography shows very high stiffness with ARFI velocity beyond the measurable range recorded as X.XX m/s (≥6.0 m/s)
ARFI: acoustic radiation force impulse
