Abstract
First described in 2000, nephrogenic systemic fibrosis (NSF)/nephrogenic fibrosing dermopathy (NFD) is a recently defined and sometimes fatal condition that, so far, has occurred only in people with some degree of renal failure, either during the conservative phase of chronic renal disease, the dialysis phase, or the kidney transplantation phase. The association between NSF/NFD and gadolinium-based magnetic resonance (MR) examination is so strong that public health agencies have sent out warnings concerning the use of gadolinium-enhanced MR in patients with renal failure. The prolonged residence of some gadolinium-chelates in the uremic milieu may allow free toxic gadolinium released from its chelate to extravasate into the extravascular space where it may accelerate fibrillogenesis. The medical community must be apprised of the concern surrounding the use of gadolinium contrast agent in patients with even moderate renal failure, considering that the number of at risk persons is 20 times greater than that of patients needing dialysis/ transplantation, remember that the risk is particularly high in patients with liver transplantation in the presence of functional renal impairment, and not to forget that MR examination remains one of the three pillars of molecular medicine.
