Gadolinium-associated nephrogenic systemic fibrosis

Area of Science:

• Radiology
• Nephrology
• Toxicology

Background:

• Magnetic Resonance Imaging (MRI) is a common diagnostic tool.
• Gadolinium-based contrast agents (GBCAs) are frequently used in MRI.
• Concerns exist regarding potential adverse effects of GBCAs, particularly in patients with impaired kidney function.

Purpose of the Study:

• To review the risks associated with gadolinium-based contrast agents.
• To provide guidance on the judicious use of MRI in patients with renal dysfunction.
• To emphasize the importance of essential diagnostic information for ordering MRI.

Main Methods:

• Literature review of studies on gadolinium toxicity.
• Analysis of clinical guidelines for MRI use in renal impairment.
• Discussion of risk-benefit assessment for contrast-enhanced MRI.

Main Results:

• Gadolinium deposition in the body has been reported following GBCA administration.
• Nephrogenic systemic fibrosis (NSF) is a severe complication linked to older GBCAs in patients with severe renal dysfunction.
• Long-term effects of gadolinium retention are still under investigation.

Conclusions:

• Physicians should exercise caution when ordering MRI scans with GBCAs for patients with renal dysfunction.
• MRI should only be performed if the diagnostic information is essential and cannot be obtained otherwise.
• Alternative imaging modalities or non-contrast MRI should be considered when feasible.
