The Contrast Media Safety Committee (CMSC) of the European Society of Urogenital Radiology (ESUR) has updated its 1999 guidelines on contrast medium-induced nephropathy (CIN).
Topics reviewed include the definition of CIN, the choice of contrast medium, the prophylactic measures used to reduce the incidence of CIN, and the management of patients receiving metformin.
• Definition, risk factors and prevention of contrast medium induced nephropathy are reviewed.
• CIN risk is lower with intravenous than intra-arterial iodinated contrast medium.
• eGFR of 45 ml/min/1.73 m2is CIN risk threshold for intravenous contrast medium.
• Hydration with either saline or sodium bicarbonate reduces CIN incidence.
• Patients with eGFR ≥60 ml/min/1.73 m2receiving contrast medium can continue metformin normally.
