Acoustic radiation force impulse of the liver

Liver cirrhosis noninvasive assessment with Acoustic Radiation Force Impulse Imaging.

 Usefulness of acoustic radiation force impulse and fibrotest in liver fibrosis assessment after liver transplant.

UNLABELLED  Background and rationale. Acoustic radiation force impulse (ARFI) is a non-invasive tool used in the evaluation of liver fibrosis in HCV positive immune-competent patients. This study aimed to assess the accuracy of ARFI in discriminating liver transplanted patients with different graft fibrosis severity and to verify whether ARFI, eventually combined with non-invasive biochemical t...

Acoustic Radiation Force Impulse (ARFI) of the pancreas

How efficient is acoustic radiation force impulse elastography for the evaluation of liver stiffness?

BACKGROUND In chronic liver diseases, a correct estimation of the severity of liver fibrosis is important for recommendations regarding the treatment. Nowadays, evaluation of fibrosis is done by noninvasive methods such as biochemical scores and transient elastography instead of liver biopsy. The lack of sensitivity to detect fibrosis, because of its heterogeneity is a drawback of liver biopsy ...

Factors that influence the correlation of acoustic radiation force impulse (ARFI), elastography with liver fibrosis.

AIM To establish the influence of different factors on the correlation between liver stiffness (LS) measurements by ARFI and liver fibrosis, evaluated by liver biopsy (LB). We assessed the following factors: the success rate (SR) and interquartile range (IQR) interval, the place where ARFI was performed, liver steatosis, the quality of the specimen obtained by LB. METHODS We studied 471 patie...
