Fibrosis is one of the hallmarks of inflammatory and repair processes in pathology. Various exogenous and endogenous stimuli, including tumor development, can induce inflammatory reactions. During the post-equilibrium phase after IV injection of non specific contrast media, CT and/or MR allow the study of these inflammatory answers to tumoral or infectious processes. Delayed enhancement of collagenic fibrous tissue during the late post-equilibrium phase is an essential complementary data in the characterization of many liver lesions: cirrhosis, cholangiocarcinoma, focal nodular hyperplasia, fibrous metastasis. but also for the differential diagnosis of pancreatic diseases (groove pancreatitis vs ductal adenocarcinoma) or of gastro-intestinal diseases (gastric adenocarcinoma vs lymphoma, mechanical complication vs inflammatory bouts of ileal Crohn's disease).
