Role of Acoustic Radiation Force Impulse Elastography in the Characterization of Focal Solid Hepatic Lesions.

Objective: The purpose of the study is to investigate the usefulness of acoustic radiation force impulse (ARFI) elastography in the characterization of focal solid liver lesions as benign, malignant, or metastatic using ARFI two-dimensional (2D) imaging and ARFI quantification (shear wave velocities [SWVs]).

Materials And Methods: Sixty lesions were included in this study. The lesions were classified into three groups: Group I included benign lesions ( = 25), Group II included malignant lesions ( = 27), and Group III included metastatic lesions ( = 8).
