Gadolinium, a rare earth metal, is used to as a “contrast agent” to improve the quality of images in around 30% of MRI scans. But some patients claim they have experienced debilitating pain, chronic fatigue and involuntary muscle spasms after being injected with the chemical.

Does contrast dye cause fatigue?
The side effects patients are reporting now include joint pain, muscle fatigue and cognitive impairment that can last for years. The gadolinium used in the dye is anchored to a molecule to create a nontoxic compound.
Is it normal to feel tired after a CT scan with contrast?
The contrast medication may be injected prior to the procedure or during the procedure. The CT technologist will be in an adjacent room where the equipment controls are located. However, they will be able to see your child through a large window and will be monitoring him or her constantly during the procedure.
What are the side effects of contrast dye?
Iodine-based Contrast Materials
- nausea and vomiting.
- headache.
- itching.
- flushing.
- mild skin rash or hives.
How long does it take for contrast dye to leave 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.
Does gadolinium make you tired?
Conclusions: We found that the onset of new symptoms within 24 hours after exposure to gadolinium-based contrast agent was more frequent than after uMRI. Among GDD-like symptoms, fatigue and mental confusion were the most frequent symptoms reported after eMRI.
Why does contrast dye make you feel warm?
A CT scan is a very low-risk procedure. Some people experience a feeling of warmth throughout their body or the urge to urinate after receiving intravenous (IV) contrast material. These are normal and temporary reactions that go away once the scan is complete and the contrast material has passed through your system.
Why do I feel weird after a CT scan?
The risks are related to allergic and non-allergic reactions to the injected contrast. Minor reactions to the IV contrast used for CT scan may include nausea, vomiting, headache or dizziness, which are usually of short duration and usually require no treatment.
Can you fall asleep during a CT scan?
Some people fall asleep during the procedure. When the imaging is complete, the scanner will send the resulting information to a computer. The computer then generates a number of images that will be reviewed by a specially-trained radiologist. Your doctor will receive a detailed report of the findings in 2-3 days.
Can you be asleep during a CT scan?
Yes, CT imaging is considered a safe examination. In general, the diagnostic benefit of a CT scan usually outweighs the risk of X-ray radiation exposure or injections of imaging contrast and use of sedatives during the scan.
Are CT scans with contrast accurate?
Sensitivity, specificity and diagnostic accuracy were 95%, 96% and 96%, respectively, in two studies of scanning with both rectal and oral contrast, and 93%, 93% and 92%, respectively, in seven studies of scanning with oral plus IV contrast.
What does gadolinium do to the brain?
Gadolinium enhances the quality of MRI by altering the magnetic properties of water molecules that are nearby in the body. Gadolinium can improve the visibility of specific organs, blood vessels, or tissues and is used to detect and characterize disruptions in normal physiology.
Does IV contrast have side effects?
Dose-dependent, systemic adverse reactions to contrast material include nausea and vomiting, a metallic taste in the mouth, and generalized warmth or flushing. These reactions are usually nonlife-threatening, self-limited problems.
Is contrast dye injection painful?
Occasionally the injection may leak out from the vein to the tissues under the skin – this is known as extravasation. If this has happened, you will experience a stinging sensation where the contrast has gone into the tissue and it can be painful. This will usually wear off after about 30 minutes.
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.
Is MRI with contrast safe?
While there’s a low risk of side effects and allergic reactions, gadolinium, the contrast agent used for MRIs, is considered safe for most people. However, for pregnant women and people with kidney disease, an MRI with contrast could cause serious problems.
Do MRIS make you tired?
There are no known side effects from an MRI scan. Patients with claustrophobia or anxiety may be given a sedative medicine to relax during the process and any medication can have side effects.
Does gadolinium stay in the brain?
It has been found that small amounts of gadolinium may be retained in the body, including the brain, bones, skin and other parts. The period of retention may be months to years. A 2017 FDA communication found that all forms of GBCAs were associated with the retention, although they found no evidence of harm caused.
What does gadolinium feel like?
Will I feel anything when I have a gadolinium contrast medium injection? Most patients do not notice any sensations, although a few patients will report a cold feeling in the arm during the injection, which is of no significance. An even smaller number (between about 1 and 4 in 100) will notice mild nausea or headache.
What are the side effects of a CT scan with contrast?
Side effects of iodine contrast can include: skin rash or hives. itching. headache.
Possible side effects of an abdominal CT scan
- abdominal cramping.
- diarrhea.
- nausea or vomiting.
- constipation.
Does contrast make poop?
If you are given contrast by mouth, you may have diarrhea or constipation after the scan. Otherwise, you don’t need any special care after a CT scan of the abdomen. You may go back to your usual diet and activities unless your healthcare provider tells you differently.
