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

Table 1 Diagnostic results of conventional ultrasound and maximum elasticity, n (%)

	Conventional ultrasound		Emax
	Benign	Malignant	Benign	Malignant
Benign, n = 48	39 (81.3)	9 (18.8)	44 (91.7)	4 (8.3)
Malignant, n = 56	11 (19.6)	45 (80.4)	4 (7.1)	52 (92.9)

Emax: Maximum elasticity.
