Clinical feasibility of liver elastography by acoustic radiation force impulse imaging (ARFI)

2011 Digestive & Liver Disease 43;6 (491-497)

BACKGROUND: Transient elastography is increasingly used for assessment of liver fibrosis. Acoustic radiation force impulse imaging (ARFI) is a new technology to perform liver elastography. AIMS: We evaluated the clinical feasibility, validity and accuracy of the ARFI method and compared it to Fibroscan((R)) and liver histology. METHODS: Ultrasonographic elastography of the liver using ARFI was performed in 29 patients with liver cirrhosis, 70 patients with liver disease and 23 healthy controls. RESULTS: ARFI was feasible in all patients providing a mean propagation velocity of 1.65+/-0.93 m/s. ARFI results of the right and left liver lobes were comparable (p
