is it dangerous doing an MRI on the brain? I was told there is no radiation but what are some other possible negative side effects and does it matter if it's done with or without contrast? The one the doctor wants me to do is without contrast.

As far as I know (no, I'm not a doctor) there are no dangers or side effects to an MRI scan. There can be allergic reactions to the contrast, but if you aren't having that, no worries.


Having said that, the biggest complication I have with MRI's is the claustrophobia.

what are the allergic side effects of the contrast and how long will it last? and does this mean without contrast there are no allergic side effects?

To be honest, I'm not sure. If you google MRI contrast agents you can look up what they typically use and what the reactions could be.


And yes, without contrast there are no allergic side effects to an MRI. And I don't mean to insult you at all, but you do know what MRI means, right? MRI = Magentic Resonance Imaging. Basically you are put into a "tube" and huge magnets rotate around you to generate an image. You don't see the magnets, but you do hear the noises from the machine. If you aren't allergic to magnets, you will have no allergic reactions to the test itself.

If you have metal in your brain you might have problem but then again if that is the case you have problem. Magnetic resonance imaging (MRI), the procedure does not use radiation.

I've had number of MRI's of my brain and unless you can link Parkinson't to the MRI, I"ve never had an ill-effect from any of them. An MRI is morelikely to save you life than cause you any harm.

No ionizing radiation is correct. You will be questioned on any metal in your body along with a medical history. Any history of metal in your eyes usually requires an x-ray before the MRI. Any implants are rated as safe, unsafe or conditional and will be assessed before you go in the magnetic field. Even though MRI's are considered safe, many facilities will not scan pregnant women in the first trimester unless deemed a medical necessity/emergency.

As far as contrast, like all medications, you can have an allergic reaction ranging from a headache, nausea, rash to full anaphalactic shock and death. The reaction rates are low as seen here:

There is also recent concerns about gadolium, the contrast ingredient, being left in the body/brain after scans in research studies and whether there are clinical effects from it.

Having contrast is not always helpful, your medical history and what your doctor is ruling out will determine if it's needed. If your doctor has ordered the scan without contrast, your insurance authorization will be for that only and you will not get contrast.

Whether an MRI is dangerous depends on how capable you are of giving a complete history of surgeries, implants and any possible metal in your body and whether you are having it done at an accredited MRI outpatient facility/hospital with licensed technologists and board certified radiologists to read the scan.
