Liver ischemia: There are 2 blood supplies to the liver. The portal vein which supplies about 80% and the hepatic artery which supplies about 20%.

Not in normal range: Upper limits of nor\mal is 1.2 cm main portal vein diameter. Distention may indicate blood not flowing noramlly through the liver. Cirrhosis is one cause. The direction of flow and waveform on Doppler ultrasound may be helpful. CT may show collateral vessels, shunts, and other abnormalities.

I have an ultrasound showing enlarged liver measuring 16.9 CM with raised echogencity, c.b.d, portal vein, ivc & hepatic veins are normal.

Fatty liver?: Increased echogencity of liver usually related to fat deposition in overweight individuals. Nonalcoholic fatty liver disease (NAFLD) now most common cause of chronic liver disease in the U.S. Fatty liver can also occur after drinking moderate or large amounts of alcohol.

Increased /coarse hepatic parenchymal echotexture (liver parenchymal disease) with prominent portal vein and splenomegaly? Wat it means

Severe damage: When damage to the liver occurs for a long time, meaning years, the liver becomes scarred and the veins that bring blood to the liver become distended because of resistance inside the liver. This increased pressure causes the spleen to take more blood and become enlarged. This is called cirrhosis of the liver and can be due to any number of things including alcohol and viral hepatitis. ...Read more
