Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15] MRI can be made sensitive to the motion of molecules.
Metabolic dysfunction–associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD), [a] is a type of chronic liver disease. This condition is diagnosed when there is excessive fat build-up in the liver ( hepatic steatosis ), and at least one metabolic risk factor.
Liver steatosis (fatty liver disease) as seen on MRI. Multiecho MR sequence in a healthy liver (top row) and a liver with severe steatosis (bottom row) are shown. In the healthy liver, the signal does not vary much in the different echoes. In the steatotic liver, the signal varies greatly between in and out phase echoes.
The Liver Imaging Reporting and Data System (aka LI-RADS) is a quality assurance tool created and trademarked by the American College of Radiology in 2011 to standardize the reporting and data collection of CT and MR imaging patients at risk for hepatocellular carcinoma (HCC), or primary cancer of the liver cells.

Unenhanced CT or MRI usually does not show the difference in intensity between the focal nodular hyperplasia and surrounding liver except when there is marked liver steatosis that reduces the attenuation of the liver, causing focal nodular hyperplasia to be hyperattenuating when compared with the surrounding liver. In the arterial phase CT or ...
A complete blood test can help distinguish intrinsic liver disease from extrahepatic bile-duct obstruction. [19] An ultrasound of the liver can reliably detect a dilated biliary-duct system, [20] it can also detect the characteristics of a cirrhotic liver. [21] Computerized tomography (CT) can give accurate anatomical information for a complete ...
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
