Liver and spleen stiffness measured by acoustic radiation force impulse elastography for noninvasive assessment of liver fibrosis and esophageal varices in patients with chronic hepatitis B.
OBJECTIVES To evaluate the performance of liver and spleen stiffness measured by acoustic radiation force impulse (ARFI) elastography for noninvasive assessment of liver fibrosis and esophageal varices in patients with chronic hepatitis B virus. METHODS Two hundred sixty-four participants, of whom 60 were healthy volunteers (classified as stage 0), 66 were patients with chronic hepatitis B wh...
متن کاملEvaluation of Acoustic Radiation Force Impulse Imaging (ARFI) for the Determination of Liver Stiffness Using Transient Elastography as a Reference in Children.
PURPOSE Transient elastography (Fibroscan(©); (FS)) and acoustic radiation force impulse imaging (ARFI) represent noninvasive, user-friendly and quick methods providing an objective and reproducible measure of liver stiffness. The aim of the study was to evaluate cut-off values and performance of ARFI measurements in children using transient elastography as a reference. METHODS/PATIENTS A tot...

AIM This study's aimwas to determine the accuracy of the spleen stiffness value acquired using acoustic radiation force impulse (ARFI) technology, to predict the presence of esophageal varices (EVs) in patients with liver cirrhosis of various etiologies. MATERIAL AND METHODS Of the 366 enrolled patients, 192 had hepatitis B virus, 74 had hepatitis C virus, and 100 had alcohol-related cirrhosi...
متن کاملSpleen assessment by Acoustic Radiation Force Impulse Elastography (ARFI) for prediction of liver cirrhosis and portal hypertension.
AIM To establish the values of spleen stiffness (SS) assessed by Acoustic Radiation Force Impulse (ARFI) in healthy subjects and in cirrhotic patients, and to evaluate its predictive value for the presence of cirrhosis and for the presence and severity of esophageal varices (EV). PATIENTS AND METHODS Our study included 82 subjects (15 healthy volunteers, 57 cirrhotic patients, 10 with various...
متن کاملThe mean values of liver stiffness assessed by Acoustic Radiation Force Impulse elastography in normal subjects.
UNLABELLED The AIM of this paper is to establish the values of liver stiffness (LS) assessed by means of ARFI in patients without known liver pathology and considered healthy subjects. MATERIAL AND METHOD the study group was composed of 82 subjects without known liver pathology, healthy volunteers or patients from other departments of our hospital who did not have altered liver laboratory tes...
