Is gadolinium toxic to the human body?
Gadolinium is highly toxic. When used as a contrast agent, it is chemically attached to a substance known as a “chelator”, intended to quickly remove the gadolinium from the body following the scan. Recent scientific research shows that significant amounts of gadolinium stay behind and accumulate especially in the brain and bones.
What is chelation for gadolinium toxicity?
Chelation is a treatment that can be used to remove toxic levels of heavy metals from the body, although it has not been well studied as a treatment for gadolinium toxicity. Chelation is a process where doctors administer chelating agents to patients. These agents bind gadolinium and remove it from the body through the kidneys.
What is gadolinium used for?
Gadolinium is the most common compound used as an MRI contrast agent and is given either orally or intravenously. While historically it was believed that gadolinium entered your body and was excreted completely intact, research has shown that this toxic compound can actually lodge into the healthy tissues of your body.
How to get rid of gadolinium in the body?
The most obvious treatment is to try to remove the Gadolinium from your body with Chelation. Chelation therapy is a medical process that involves administering chelating agents that will bind to the metal ions to form a more chemically stable compound that can be safely excreted from the body, typically through the kidneys.

What does gadolinium do to the body?
A 2016 study in Magnetic Resonance Imaging found headaches, bone and nerve pain, and skin thickening were the most commonly reported reactions in patients that were presumed to have gadolinium toxicity. In the study of 42 people with symptoms, brain fog and headaches lasted for more than three months in 29 people.
Can you recover from gadolinium toxicity?
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.
How do I get rid of gadolinium toxicity?
Gadolinium based contrast agents (GBCAs) have been linked to toxicity in patients, regardless of having impaired or normal renal function. Currently, no therapy is considered highly effective for removing gadolinium (Gd) from the body.
Should I be worried about gadolinium?
Gadolinium has a long track record of safety However, a small amount of gadolinium doesn't put patients at risk. Gadolinium is extremely safe, with serious adverse reactions occurring in roughly 0.03 percent of all doses.
How long does it take to flush out gadolinium?
In patients with normal kidney function, most of the gadolinium contrast medium injected (over 90%) is passed out in the urine within 24 hours.

Can MRI be done without gadolinium?
The primary difference is that for contrast MRIs, a dye (gadolinium-based) is given to the patient intravenously prior to the scan. Non-contrast MRI is great option for patients for whom dye is not recommended, pregnant women and kidney-compromised patients.
How do you flush contrast out of an MRI?
Drink plenty of water after the MRI scan to help your kidneys flush the contrast out from your body. If you become unwell during the day after your scan, go to your nearest emergency department or general practitioner (GP). The kidneys remove most MRI contrast agents from your blood.
Can I refuse contrast dye for MRI?
A: As with other medical concerns, patients should speak with their doctor about their individual care decisions. Both the choice to receive contrast material and the choice to refuse contrast material when it otherwise would be indicated can have potential health consequences.
How much water should I drink after an MRI with contrast?
If you had intravenous contrast, you should drink at least eight glasses of water throughout the day to help flush the contrast out of your body. Your doctor will receive the results within 48 hours.
Should I get an MRI with or without contrast?
MRI without contrast cannot generally help in evaluating the given tumor condition. MRI images with contrast are clearer than the images of MRI without contrast. Due to the high clarity of images gathered by MRI with contrast, they are easier for a medical specialist to evaluate and interpret.

Is gadolinium toxic?
Gadolinium is highly toxic. When used as a contrast agent, it is chemically attached to a substance known as a “chelator”, intended to quickly remove the gadolinium from the body following the scan.
How Is Gadolinium Used?
Gadolinium is a metal substance that is toxic to humans on its own. Medical personnel combine Gadolinium with chemical compounds, known as chelating agents, to create Gadolinium-based Contrast Agents (GBCAs). Before an MRA or MRI, the medical professional will inject a GBCA intravenously into your body.
Why Is Gadolinium Harmful?
Medical personnel claim that GBCAs only live 90 to 120 minutes within patients’ bodies. However, emerging research and recent medical malpractice claims show that the Gadolinium in the GBCA may live in the body for years after the procedure.
Compensation for Gadolinium Toxicity Victims
If you develop Gadolinium toxicity after an MRI or MRA, you may be eligible for a lawsuit against the manufacturer of the GBCA. Through this claim, you can collect compensation for the damages you suffered due to the Gadolinium toxicity, which may include the following.
How to remove Gadolinium from the body?
The most obvious treatment is to try to remove the Gadolinium from your body with Chelation . Chelation therapy is a medical process that involves administering chelating agents that will bind to the metal ions to form a more chemically stable compound that can be safely excreted from the body, typically through the kidneys. Most Chelation is done without FDA approval of the chelating process. Although ethylenediaminetetraacetic acid (EDTA), and specifically Calcium EDTA is the agent we have seen used most often in doctor-controlled IV Chelation to remove Gadolinium, it is only approved by the FDA for removal of lead. Nonetheless, Chelation therapy is practiced every day by doctors providing alternative or integrative medical services, and is best done under their supervision because the chelating agent can also remove important nutrients like calcium and zinc from the body.
What is the best way to remove Gadolinium?
Some patients looking for a more natural way to remove the Gadolinium have studied the chelating properties of foods and have focused on foods that they are hopeful will help. Herbs such as cilantro and garlic, pectin and chlorella, and supplements such as Alpha Lipoic Acid (ALA) and N-Acetyl-Cysteine (NAC) have some chelating properties and may be worthy of additional research.

In our Survey of Chronic Symptoms of Gadolinium Toxicity, 100% of the participants reported Pain as one of their top symptoms. Pain can reorient your lifestyle, and cause you both mental and physical distress. Our only advice is to consider symptom relief carefully, and do not try to be the hero who says “I can tough it out”. Both of the website authors take prescribed medications for pain, and although neither is totally pain free, both are able to live a fairly normal life as a result of living with less pain on a daily basis.
