The potential of iosulamide meglumine as a contrast material for intravenous cholangiography: an experimental study in dogs.

abstract：RATIONALE AND OBJECTIVES:High signal intensity in the basal ganglia on T1-weighted MR imaging has been reported in chronic manganese (Mn) poisoning. However, the exact meaning of the high signal intensity remains unclear: does it result from Mn itself, secondary pathologic changes of the brain tissue, or both? The goal...
