Evaluation of Acoustic Radiation Force Impulse (ARFI) imaging and contrast-enhanced ultrasound in renal tumors of unknown etiology in comparison to histological findings

Abstract

ARFI imaging improves visualization of unclear renal masses in comparison to fundamental B-scan and adds new information about the tissue stiffness in a less time-consuming and more reproducible way. CEUS with SonoVue allows an early evaluation of renal masses or complex cysts.
