Regent D, Laurent V, Antunes L, Debelle L, Cannard L, Leclerc J, Beot S. J Radiol 2002 Feb;83(2 Pt 2):292-308
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).
