Comparison Between <scp>SonoVue</scp> and Sonazoid <scp>Contrast‐Enhanced</scp> Ultrasound in Characterization of Focal Nodular Hyperplasia Smaller Than 3 cm

Abstract

Contrast-enhanced ultrasound enables an accurate diagnosis in FNH smaller than 3 cm. Sonazoid CEUS and SV CEUS were comparable in diagnosing small FNH, and both agents were highly capable of depicting the centrifugal filling dynamic process of FNH smaller than 3 cm. Sonazoid CEUS might be better than SV CEUS at depicting a central scar.
