Abstract

Intravenous iodinated contrast is used in many contrasted imaging studies ranging from computed tomography to angiography. The risks of contrast-induced nephropathy (CIN) and its incidence have not been clearly defined. Most iodinated contrast media used today are hypertonic compared with serum osmolality and pose biological risks. However, the risk of CIN in the general population may be overestimated. Confounding risk factors may contribute to acute kidney injury other than attributable risk of contrast exposure. In high-risk populations such as in those with CKD, CIN risk may be higher and thus caution should be exerted with contrast exposure. The volumes of contrast should be minimized as much as possible and hemodynamic status should be optimized before contrast administration.
