Screening of kidney function before contrast-enhanced CT
Abstract
Iodine-based contrast agents are routinely used for contrast-enhanced CT. However, CT contrast has been associated with acute kidney injury (CA-AKI) and thus international guidelines recommend prior screening of kidney function using eGFR. However, eGFR screening is resource-consuming, and current evidence suggests that the risk of CA-AKI is very low. This review examines the evidence, recommendations, and current practices of eGFR screening in Danish radiology departments. Following a Choosing Wisely-strategy, we recommend minimising eGFR screening before contrast-enhanced CT scans.
