Liver contrast enhanced ultrasound perfusion imaging in the evaluation of chronic hepatitis C fibrosis: preliminary results.

We wanted to determine whether liver contrast-enhanced ultrasound (CEUS)-derived peak signal intensity (PSI) and peak signal intensity/time (PIT) predict liver fibrosis in chronic hepatitis C (CHC). Forty-nine patients with CHC (METAVIR classification) and 10 control subjects were included in the study. After a bolus of 2.

New type of asymptomatic congenital portosystemic shunt.

Congenital extrahepatic portosystemic shunt (CEPS) is an extremely rare anomaly. In these malformations splanchnic blood bypasses the liver and drains into the systemic circulation through the inferior vena cava (IVC) or the left renal vein (LRV). Extrahepatic shunts may be divided into type 1 [end-to-side mesenterico-caval fistula with congenital absence of the portal vein (PV)] and type 2 (partial portocaval shunt caused by side-to-side mesenterico-caval fistula with normal or hypoplasic PV).

Percutaneous cryoablation of small hepatocellular carcinoma with US guidance and CT monitoring: initial experience.

The purpose of this study was to retrospectively determine the safety and effectiveness of percutaneous cryoablation, monitored with computed tomography (CT) and ultrasonographic (US) guidance, for the treatment of hepatocellular carcinoma (HCC). Four patients with small HCCs underwent one percutaneous cryoablation treatment session monitored with CT and US guidance. All patients underwent pretreatment blood chemistry testing and imaging evaluation.
