Abstract
In the past, a high percentage of hospital-acquired renal failure was attributed to contrast media. That position is now very controversial. Recently, doubts have been raised regarding the real relationship between acute kidney injury and intravenous contrast media administration. Similarly, statements about specific methods of preventing contrast-inducing nephropathy have been challenged. This review article addresses the controversies of incidence, causation, and prevention in an attempt to help the practicing radiologist adopt methods for their own department.
Key Points
• The reported CIN incidence ranges from 2–12 % following contrast-enhanced CT.
• Studies without a non-contrast CT control group may overestimate CIN incidence.
• Development and application of a comprehensive CIN prevention strategy is recommended.
