Color and power doppler, before and after contrast media, in the diagnosis of focal nodular hyperplasia and hepatocellular adenoma
文摘
Objective. The aim of this study is to evaluate the vascular characteristics of Focal Nodular Hyperplasia (FNH) and Hepatocellular Adenoma (HA) by Color Doppler (CD) and Power Doppler (PD), as well as the possibility of differential diagnosis between these two forms, and diagnostic improvement obtainable by means of a galactose-based contrast agent (Levovist).
