Abstract: 【Abstract】Acute kidney injury is one of the most common adverse reaction after intravascular administration of contrast media, especially with increased risk in kidney disease patients. How to reduce the risk has always been an important issue in clinical practice. In January 2020, the American College of Radiology and the National Kidney Foundation issued consensus statements about use of iodinated contrast media in patients with kidney disease. These statements update the definition, diagnostic criteria, risk factors, combined use of drugs, preventive measures, special population and other aspects. This paper interprets these statements in association with other guidelines and relevant literature.

Key words: Iodinated contrast media, Acute kidney injury, Chronic kidney disease
