Gadolinium is currently the only heavy metal suitable for MRI enhancement..
How long does gadolinium stay in the body?
With normal kidney function, most of the gadolinium is removed from your body in the urine within 24 hours. If you have acute renal failure or severe chronic kidney disease and receive a gadolinium-based contrast agent, there may be a very small risk of developing a rare condition.
How bad is Gadolinium?
The concerns focus on gadolinium, a rare-earth metal used in some of the most effective dyes. It is well known that it can trigger a rare, dangerous condition called nephrogenic systemic fibrosis in people with kidney disease. Gadolinium can also cause an allergic reaction.
Does gadolinium stay in the brain?
Residual gadolinium is deposited not only in brain, but also in extracranial tissues such as liver, skin, and bone.
How do you detox from gadolinium?
There is no current available method of gadolinium detoxification to help lessen the toxicity in patients who suffer from this problem. In some cases, gadolinium can be retained in a patient’s body for months or even years after the MRI, which can cause serious and lasting side effects.
Does gadolinium toxicity go away?
Gadolinium retention and toxicity is a progressive disease. Several treatments are available if the condition is caught early, but often the disease is not curable. Gadolinium retention only occurs in patients who have received a gadolinium-based contrast agent.
