Value of shear wave elastography with maximal elasticity in differentiating benign and malignant solid focal liver lesions

Figure 1 Region of interest in the liver in volunteers and in patients with focal liver lesions using virtual touch tissue quantification. A: Region of interest (with fixed size 10 mm × 5 mm) for the liver in volunteers was placed at a depth of 4-6 cm, and tubular structures, such as portal veins, hepatic veins and intrahepatic bile ducts were carefully avoided; B: Region of interest for patients was placed inside the targeted focal liver lesion (a hemangioma shown here).
