Table E1. Detection Rate of 208 Focal Liver Lesions in 53 Patients with Diffusion-weighted and T2-weighted Imaging Stratified by Location in Liver and Averaged for Two Independent Observers  

 

	Right Liver Lobe (n = 125)	Left Liver Lobe (n = 83)	P Value
Diffusion-weighted imaging	110.5 (88.4)	71.5 (86.1)	.509
T2-weighted imaging	94.0 (75.2)	51.0 (61.4)	.037
P Value	.0022	.00013

 

Note.—Three lesions bridging the right and left lobes were excluded. Numbers in parentheses are percentages.
