Contrast-induced nephropathy (CIN) is a purported form of kidney damage in which there has been recent exposure to medical imaging contrast material without another clear cause for the acute kidney injury. Despite extensive speculation, the actual occurrence of contrast-induced nephropathy has not been demonstrated in the literature. [1]
Nephrogenic systemic fibrosis is a rare syndrome that involves fibrosis of the skin, joints, eyes, and internal organs. NSF is caused by exposure to gadolinium in gadolinium-based MRI contrast agents (GBCAs) in patients with impaired kidney function.
While NSF is a severe form of disease, gadolinium deposition disease (GDD) is a mild variant with pain (e.g. headache), fatigue, and / or gadolinium depositions. [ 26 ] As a free solubilized aqueous ion, gadolinium(III) is highly toxic, but the chelated compounds are generally regarded as safe for individuals without kidney disease.
Gadodiamide is a contrast medium used for cranial and spinal magnetic resonance imaging (MRI) and for general MRI of the body after intravenous administration. It provides contrast enhancement and facilitates visualisation of abnormal structures or lesions in various parts of the body including the central nervous system (CNS).
In patients with kidney failure, there is a risk of a rare but serious illness called nephrogenic systemic fibrosis (NSF) [61] that is caused by the use of gadolinium-based contrast agents. The disease resembles scleromyxedema and to some extent scleroderma. It may occur months after a contrast agent has been injected.
The most severe reaction to gadobutrol is nephrogenic system fibrosis (NSF) among patients with impaired elimination of the drug. The risk is highest among patients with chronic, impaired kidney function and those with acute kidney injury. NSF may result in death or severe impairment of the skin, muscle, and internal organs.

Think about the healthy life years you gain just from minimizing these risks, considering lung cancer and heart disease are by far the leading causes of premature deaths among men and women in the US.
A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. [1] Contrast agents absorb or alter external electromagnetism or ultrasound , which is different from radiopharmaceuticals , which emit radiation themselves.
