Nephrogenic Systemic Fibrosis Disappeared After Restrictive Use of Gadolinium?

According to a large (50 000+) retrospective cohort of patients who underwent contrast-enhanced MR examinations at a single academic institution pre- and post-adoption of strict gadolinium guidelines:-
  • No new cases of nephrogenic systemic fibrosis (NSF) were diagnosed
  • During the pre-guidelines adoption and transitional period, the incidence of NSF was 3 cases per 10,000 contrast-enhanced MRI
  • After the adoption of guidelines, the incidence was 0 per all examinations
The Guidelines for Imaging Adult Patients
  • Based on renal disease severity
  • eGFR 60 or greater - GBCA can be administered as indicated
  • eGFR 30-59 - weight-based dose of GBCA (0.2 mL/kg) can be administered with maximal dose of 20 mL allowed within 24 hours
  • eGFR less than 30 - GBCA cannot be administered except in cases of medical necessity; informed consent required; nephrology consultation required; hemodialysis should be considered
  • Very rarely that any patients with eGFR less than 30 would get contrast-enhanced MR exams (36 in 52 954 exams; 0.07%)
eGFR = estimated glomerular filtration rate; GBCA = gadolinium-based contrast agent
