I have never liked the use of contrast agents.

From wikipedia:
"The gadolinium(III) ion occurring in water-soluble salts is quite toxic to mammals. However, chelated gadolinium(III) compounds are far less toxic because they carry gadolinium(III) through the kidneys and out of the body before the free ion can be released into tissue. Because of its paramagnetic properties, solutions of chelated organic gadolinium complexes are used as intravenously administered gadolinium-based MRI contrast agents in medical magnetic resonance imaging. However, in a small minority of patients with renal failure, at least four such agents have been associated with development of the rare nodular inflammatory disease nephrogenic systemic fibrosis. This is thought to be due to the gadolinium ion itself, since gadolinium(III) carrier molecules associated with the disease differ."

I would get copies of my images and specifically look at the kidneys for any buildup.

Also from https://gadoliniumtoxicity.com/help/treatments/ :

"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."

Also:

"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."
