How tissue injuries progress among organs during LPS-induced fulminant hepatic failure remains to be elucidated, especially during the very acute phase of small animal models. We have addressed this problem in LPS/D-galactosamine-induced fulminant hepatitis by using sequential micro-MRI scanning. Analysis of T2-weighted MRI signal intensities detected tissue injury in the liver during the early phase (as early as the 3 h timepoint), at which point histological examination revealed only minor morphological changes in hepatic tissues.
In the pancreas, increases in the T2-weighted signals were made readily apparent by the pancreatic edema formation that was determined by histological examination. Only minimal pathologies were observed in the renal cortex based on micro-MRI and histo... view more»
