Acute kidney injury from contrast CT scans: Is there an association?
from Medscape (free login required)
One common concern emergency medicine professionals face is the risk for acute kidney injury (AKI) secondary to the use of intravenous (IV) contrast for CT studies. Currently, emergency medicine professionals typically avoid the use of CT scans with IV contrast before checking renal function, and the use of IV contrast is discouraged for patients who have abnormal renal function. There have been studies in the literature recently that have evaluated this circumstance and have suggested that perhaps AKI related to IV contrast may not be as much of an issue as we have all thought.
