MR appearance of extravasated gadolinium contrast medium

DA Carrier, JJ Ford and LA Hayman
Radiology Department Baylor College of Medicine, Houston, Texas 77030.

The authors consider the physics behind this paradoxical decrease in signal intensity where there are high concentrations of gadopentate dimeglumine.
