Abstract

The comparison of biphasic contrast-enhanced CT and contrast-enhanced B-mode wideband (PIDHI) in the characterization of focal liver lesion (FLL) is discussed. A marked increase in post-contrast echogenicity of large and small tumoral vessels and improvement of vessel-to-tumor contrast obtained in all cases, with no artifacts. Marked liver parenchyma enhancement mostly in the late phase. Ultrasound and CT enhancement patterns almost superimposable. Hepatocellular carcinoma (HCC) and focal nodular hyperplasias (FNH) showed marked arterial enhancement, with fast decrease in portal venous phase, while hemangiomas appeared as vascular volume voids with discrete peripheral puddling. All colorectal metastases showed a lower enhancement than normal liver.
