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...
متن کاملRole of Acoustic Radiation Force Impulse (ARFI) Elastography in Determination of Severity of Benign Prostate Hyperplasia
BACKGROUND The aim of this study was to investigate the potential contribution of acoustic radiation force impulse (ARFI) elastography to the determination of the severity of benign prostate hypertrophy (BPH) by performing shear wave velocity (SWV) measurements of the prostate using ARFI technology. MATERIAL AND METHODS Sixty BPH patients and 40 healthy volunteers were included in this study. S...
متن کاملAcoustic Radiation Force Impulse (ARFI) and Transient Elastography (TE) for evaluation of liver fibrosis in HIV-HCV co-infected patients
BACKGROUND Transient elastography (TE) is widely used for non-invasive assessment of liver fibrosis in HIV-HCV co-infected patients. TE, however, cannot determine liver morphology. Acoustic radiation force impulse (ARFI) imaging is a novel procedure enabling assessment of liver fibrosis during a conventional ultrasonographic examination. This study evaluated the correlation between liver fibros...
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 کاملMagnetic resonance acoustic radiation force (impulse) imaging (MR-ARFI)
Background/introduction MR-ARFI adds to the rich toolbox of MR imaging methods for guiding focused ultrasound. MRI has exquisite soft tissue contrast for targeting focused ultrasound and a variety of contrast mechanisms for assessing the effect of focused ultrasound. In addition, MR can provide temperature mapping in near-realtime. MR-ARFI is an imaging method that compliments these other capab...
