Differential diagnosis of different types of solid focal liver lesions using two-dimensional shear wave elastography

Figure 1 Two-dimensional shear wave elastography images in patients with focal liver lesions. A: Tumor shown on quality mode as green indicated that the quality of two-dimensional shear wave elastography image was up to standard; B: Tumor shown in velocity mode, speed bar set at 0.5-4.0 m/s; C: Two circular regions of interest (ROIs, with 3 mm diameter) placed at the stiffest site in the tumor and at the periphery of tumor; D: Maximum values of the two ROIs recorded as maximal elasticity.
