Echogenicity of hepatic versus portal vein walls revisited ...

The portal vein wall typically is hyperechoic over a wide range of beam-vessel angles, whereas the hepatic vein wall is hyperechoic only when the incident beam and the vessel are perpendicular. This has been attributed to marked discrepancies in mural thickness, collagen content, or perivascular fat between portal and hepatic veins. We evaluated histologically the walls of …

Portal venous gas | Radiology Reference Article ...

02.05.2008 · Gas in the portal veins usually manifests as echogenic mobile foci in the lumen of the portal vein. Doppler US will demonstrate sharp spikes on both sides of the basal line on the Doppler spectral display 7. CT. Similar to x-ray features, portal venous gas manifests on CT as branching gaseous foci of low density in the liver, portal vein and its tributaries. The vessel-gas …

Air in the portal vein: sonographic and Doppler ...

Three patients with portal venous gas (one with radiographic and computed tomographic findings) had similar sonographic and Doppler patterns in the portal vein (PV). These patterns consisted of hyperechogenic foci moving within the lumen of the PV, producing sharp bidirectional spikes superimposed on the usual Doppler tracing of the PV. An injection of 0.25 …

Sonographic Evaluation of the Portal and Hepatic Systems

The portal veins can be differentiated sono-graphically from the hepatic veins by the bright echogenic walls that surround them. This is due to the thick collagenous tissue in the portal vein walls. The hepatic veins do not exhibit echogenic borders (Fig. 1). The cystic vein, which drains into the gallblad-der, is a branch of the portal vein. Although it is

Echogenic Liver: What Does It Mean? | Fatty Liver Disease

10.08.2021 · An echogenic liver is an ultrasound reading that indicates a higher level of fat in the liver. A high content of fat in the liver is indicative of fatty liver disease. Although fatty liver disease may progress, it can also be reversed with diet and lifestyle changes. When striving to protect your liver, aim to drink lots of water, eat high-quality protein, and lots of veggies. Losing …

Ultrasound Evaluation of the Portal and Hepatic Veins ...

23.09.2016 · Ultrasound is also an excellent means of evaluating patients for portal vein (PV) thrombosis and Budd-Chiari syndrome (BCS), which may precipitate acute deterioration of liver function in patients with cirrhosis and HCC. In addition, duplex Doppler ultrasound has an important clinical role in monitoring patients following placement of transjugular intrahepatic …
