Diffusion-Weighted Imaging with Two Different -Values in Detection of Solid Focal Liver Lesions

Table 5

Detection rate of solid FLLs with each sequence stratified by location and size.

Sequence		Lesion location		Lesion size
		Left lobe ()	Right lobe ()	≤10 mm	>10 mm
DWI600		79.3 (32.5/41)	67.7 (65/96)	31.2 (7.5/24)	79.6 (90/113)
DWI100		70.7 (29/41)	66.7 (64/96)	25 (6/24)	77.0 (87/113)
T2WI		76.8 (31.5/41)	56.3 (54/96)	16.7 (4/24)	72.1 (81.5/113)
value	DWI100 versus DWI600	0.411	0.878	0.588	0.628
	DWI100 versus T2WI	0.573	0.138	0.477	0.382
	DWI600 versus T2WI	0.794	0.102	0.212	0.175

Data are averaged for two independent observers. Unless otherwise indicated, numbers are percentages, with raw data in parentheses. DWI600: diffusion-weighted imaging with -value of 0, 600 sec/mm²; DWI100: diffusion-weighted imaging with -value of 0, 100 sec/mm²; T2WI: T2-weighted imaging.
