Incidence and predictors of contrast-induced nephropathy following CT-angiography for clinically suspected acute pulmonary embolism

摘要

Contrast-induced nephropathy (CIN) is a decrease in renal clearance following injection of radiographic iodinated contrast media (CM) in the absence of other etiologies and is a potential cause of acute kidney injury (AKI) [1]. The reported incidence of CIN ranges between 6.5 and 19%, depending on the population, procedure-related risk factors and different criteria for AKI and CIN. If CIN occurs, it can not be treated and is associated with mortality and an increased length of hospital stay [1-3].
