New method for assessing liver XXXX based on acoustic radiation force impulse: a special reference to the difference between right and left liver.

@entity1 @entity82 @entity3145 @entity409 @entity492
BACKGROUND: @entity3145 ( @entity3145 ) based on acoustic radiation force impulse (ARFI) imaging has been developed as a noninvasive bedside method for the assessment of liver stiffness. In this study, we examined the diagnostic performance of ARFI imaging in 103 @entity1 , focusing on the difference in @entity3145 values between the @entity409 . METHODS: We evaluated @entity3145 values of the right and left lobes in 79 @entity1 with chronic @entity409 who underwent histological examination of liver @entity82 and in 24 healthy volunteers. The diagnostic accuracy of @entity3145 was compared with several serum markers, including hyaluronic acid, type 4 collagen, and @entity492 transaminase to platelet ratio index. RESULTS: The @entity3145 values (meters per second) in the right and left lobes were 1.61    0.51 and 1.90    0.68, respectively, and the difference was statistically significant (P < 0.0001). The @entity3145 values in both liver lobes were correlated significantly with histological @entity82 grades (P < 0.001). The standard deviations of the @entity3145 values in the right lobe were significantly lower than those in the left lobe (P < 0.001). The area under the receiver-operating characteristic curve for the diagnosis of @entity82 (F >=  3) using @entity3145 values in both liver lobes was superior to serum markers, especially in the right lobe. CONCLUSIONS: @entity3145 is an accurate and reliable tool for the assessment of liver @entity82 . @entity3145 of the right lobe was more accurate for diagnosing liver @entity82 than in the left lobe.
