Contrast-induced acute kidney injury(CI-AKI) is oneof the most common causes of AKI in clinical practice.CI-AKI has been found to be strongly associated with morbidity and mortality of the patients.Furthermore,CI-AKI may not be always reversible and it may be associated with the development of chronic kidney disease.Pathophysiology of CI-AKI is not exactly understood and there is no consensus on the preventive strategies.CI-AKI is an active research area thus clinicians should be updated periodically about this topic.In this review,we aimed to discuss the indications of contrastenhanced imaging,types of contrast media and their impact on nephrotoxicity,major pathophysiological mechanisms,risk factors and preventive strategies of CI-AKI and alternative non-contrast-enhanced imaging methods.
