To the Editor: Nephrogenic systemic fibrosis is a newly describedsystemic disorder that occurs in patients with renal insufficiency.1,2The functional consequences of nephrogenic systemic fibrosisare often devastating and may be fatal. Since nephrogenic systemicfibrosis develops after exposure to gadolinium-containing magneticresonance contrast agents in some patients,3 the Food and DrugAdministration recommended avoiding such agents in patientswith renal insufficiency. The mechanism by which nephrogenicsystemic fibrosis develops after gadolinium exposure remainsunknown.
Gadolinium is administered as a chelate, since free gadoliniumis toxic. Metals such as iron are capable of inducing the dissociationof gadolinium from . . . [Full Text of this Article]
