Contrast media are widely used in diagnostic imaging thanks to their ability to improve the Imaging quality test, they are considered full-fledged drugs and, as such, are not completely risk-free. The radiologist is responsible of contrast agent administration, so he has to know about contrast agents nature and regarding the recommendation and contraindication against the use and he also should consider the risk-to-benefit profile of the proposed contrast material - enhanced examination and confirm a valid clinical indication based on clinical indication and laboratory tests. This document describes the chemical-physical characteristics of contrast media for intravascular use and deals of the main problems related to contrast media administration. Acute post-contrast kidney injury (PC-AKI) is treated, summarizing its pathophysiological mechanisms, identifying subjects at risk and providing indications on suitable measures to prevent it. Indications are also provided regarding the use of contrast medium in pregnant and breastfeeding women and regarding the management of contrast agent extravasation. The problem concerning Gadolinium retention in tissues is addressed, from Nephrogenic Systemic Fibrosis to the Gadolinium deposit in brain tissue, also assessing this problem in categories such as women with increased risk of breast cancer who perform MRI screening. The purpose of this document is to provide the radiologist with practical indications to better manage the contrast media administration even in these particular cases.
