Real-time Contrast-enhanced and Real-time Virtual Sonography in the Assessment of Benign Liver Lesions

Abstract

Imaging techniques, in particular ultrasonography, have led to great advances in clinical hepatology in the past few decades. The introduction of second-generation contrast agents and the development of contrast specific techniques have opened new prospects in the detection and characterization of liver lesions. New hybrid imaging techniques that combine in real-time transabdominal ultrasound with other cross-sectional imaging techniques (CT or MR) might add even more valuable information in the cases with focal lesions. The aim of this review is to describe the role of real-time contrast-enhanced and real-time virtual sonography in the assessment of benign liver lesions.
