Adverse reactions to gadolinium-based contrast agents (GBCAs) occurred in 0.1% of patients. Gadofosveset trisodium showed the highest reaction rate (0.80%), while gadopentetate dimeglumine had the lowest (0.09%).
Area of Science:
- Radiology
- Pharmacovigilance
- Medical Imaging
Background:
- Gadolinium-based contrast agents (GBCAs) are widely used in medical imaging.
- Understanding the incidence and risk factors of adverse reactions is crucial for patient safety.
- This study evaluates four specific GBCAs in a large patient cohort.
Purpose of the Study:
- To assess the incidence of adverse reactions associated with four different GBCAs.
- To identify potential risk factors influencing GBCA-related adverse events.
- To compare the safety profiles of gadopentetate dimeglumine, gadofosveset trisodium, gadoxetate disodium, and gadobenate dimeglumine.
Main Methods:
- Retrospective analysis of 194,400 GBCA administrations from 2007-2014.
- Data sourced from an electronic incident reporting system at a single academic medical center.
- Adverse reactions were categorized by severity, patient type, and examination type.
Main Results:
- An overall adverse reaction rate of 0.1% (204/194,400) was observed.
- Gadofosveset trisodium had the highest reaction rate (0.80%), followed by gadoxetate disodium (0.31%), gadobenate dimeglumine (0.22%), and gadopentetate dimeglumine (0.09%).
- Significant differences in reaction rates were found between various GBCAs, with higher rates in females and outpatients.
Conclusions:
- The overall incidence of adverse reactions to the studied GBCAs is low (0.1%).
- Significant variations in adverse reaction rates exist among different GBCAs.
- Gadofosveset trisodium demonstrated a higher incidence of adverse reactions compared to other agents evaluated.
