Mean values of measured parameters for normal liver parenchyma, benign, and malignant hepatic lesions

Parameter	Normal liver parenchyma	Benign hepatic lesions	Malignant hepatic lesions	P	P1	P2
ADC (×10−3 mm2/s)	1.18 ± 0.26	1.67 ± 0.39	1.21 ± 0.4	<.001	.522	<.001
D t (×10−3 mm2/s)	0.68 ± 0.22	1.32 ± 0.49	1.13 ± 0.89	<.001	<.001	.083
D p (×10−2 mm2/s)	2.19 ± 1.24	1.44 ± 0.8	1.32 ± 0.73	<.001	<.001	.212
f p	0.32 ± 0.12	0.41 ± 0.18	0.29 ± 0.14	<.001	.053	<.001
DDC (×10−3 mm2/s)	1.41 ± 1.53	2.2 ± 1.37	1.29 ± 0.99	<.001	.407	<.001
α	0.55 ± 0.17	0.81 ± 0.18	0.8 ± 0.19	<.001	<.001	.600

Data are mean ± SD. P is normal hepatic parenchyma vs benign hepatic lesions, P1 is normal hepatic parenchyma vs malignant hepatic lesions, P2 is benign hepatic lesions vs malignant hepatic lesions. The f _p value is the fraction of D _p, which represents a perfusion‐related percentage. The α value represents the heterogeneity within the voxel size and ranges from 0 to 1.
