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

Table 1 Differences in age, gender and history of malignancy between malignant and benign groups

	Age (yr)	Gender		History of malignancy
		Male	Female	Yes	No
Malignant (n = 96)	44.68 ± 12.30	73	23	11	85
Benign (n = 31)	57.31 ± 10.36	7	24	1	30
t/χ2	5.633	28.729		1.856
P value	0.000	0.000		0.291

Table 2 Differences in age, gender and history of malignancy among three types of malignancy

	Age (yr)	Gender		History of malignancy
		Male	Female	Yes	No
CCCs (n = 16)	58.63 ± 10.37	11	5	1	15
HCCs (n = 69)	56.07 ± 10.51a	54	15	5	64
Liver metastasis (n = 11)	63.18 ± 7.55	8	3	5	6
F/χ2	2.460	0.720		14.165
P value	0.091	0.698		0.001

^aP = 0.035 vs liver metastases. CCCs: Cholangiocellular carcinomas; HCCs: Hepatocellular carcinomas.

Table 3 Differences in two-dimensional shear wave elastography results between benign and malignant focal liver lesions

	Emax of tumors (m/s)	Emax of periphery of tumors (m/s)
Malignant (n = 100)	2.21 ± 0.57	1.52 ± 0.39
Benign (n = 32)	1.59 ± 0.37	1.36 ± 0.44
t	5.781	2.073
P value	0.000	0.040

Emax: Maximal elasticity.

Table 4 Differences of two-dimensional shear wave elastography results among different types of malignant focal liver lesions

	Emax of the tumors (m/s)	Emax of the periphery of tumors (m/s)
CCCs (n = 16)	2.14 ± 0.34a	1.56 ± 0.39
HCCs (n = 72)	2.14 ± 0.46b	1.54 ± 0.37
Liver metastases (n = 12)	2.73 ± 0.99	1.36 ± 0.46
F	6.418	1.299
P value	0.002	0.277

^aP = 0.005 vs liver metastases.

^bP = 0.001 vs liver metastases.

Emax: Maximal elasticity; CCCs: Cholangiocellular carcinomas; HCCs: Hepatocellular carcinomas.
