Figure 4. Images obtained during a core biopsy. Extended field-of-view B-mode image (A) shows an irregular hypoechoic mass in the distal ulna. Color Doppler flow imaging (B) demonstrates hypervascular tumor stroma with numerous sinusoidal vessels typical for giant cell tumor of bone. On shear-wave elastography (C), the color elastogram shows predominantly blue/cyan and cyan/green readings performed on 2 small areas of the superficial aspect of the tumor stroma (areas of low to intermediate stiffness, measuring 30–60 kPa).
