What is regenerative nodule in liver?
Regenerative nodules are the most common cirrhosis-associated hepatocellular nodules (,56,,57). Round and sharply circumscribed, they are usually numerous and diffusely distributed throughout the liver; there may be from 1000 to 1,000,000 regenerative nodules in a single cirrhotic liver (,2).

What is dysplastic nodule?
A dysplastic nodule is a nodular region of hepatocytes at least 1 mm in diameter with dysplasia but without definite histologic criteria for malignancy. These nodules are usually found in cirrhotic livers. Dysplastic nodules can be low grade or high grade (,7).

Are there any regenerative nodules on a CT scan?
On post-contrast CT and MRI, regenerative nodules enhance similar to the normal liver parenchyma in both portal venous and hepatocellular/delayed phases, and thus may not be distinguishable in a cirrhotic liver. There is no arterial phase enhancement. CT. Regenerative nodules are rarely visible on non-contrast CT unless they are siderotic.
How big are the nodules on the liver?
Nodular regenerative hyperplasia is characterized by micronodular transformation of liver parenchyma, with the nodules usually 1-3 mm in size but can be larger if confluent 1. The liver surface can be smooth or irregular 1.
Where does nodular regenerative hyperplasia occur in the liver?
Nodular regenerative hyperplasia occurs throughout the liver preferentially around portal tracts 1.
