Core Tip
Core tip: The best preventive measure of contrast-induced acute kidney injury is to avoid unnecessary contrast administration which requires a good knowledge of indications and risk factors of contrast-enhanced imaging. Recently, alternative non-contrast-enhanced imaging modalities have been developed which may help us to decrease the frequency of contrast administration. In this review, these alternative modalities are discussed concisely. Type, osmolality, molecular structure and viscosity of contrast media (CM) are important determinants of nephrotoxicity. Major studies and meta-analyses comparing CM in terms of renal safety are also discussed.
