I have had four MRIs in the last six months, including one that took nearly two hours. No impact on my tinnitus, not even a little. But my anxiety before the first one? Yup, that created a short-term spike.I had a second opinion from an ENT, he said that he recommended me getting an MRI but it wasn't rushed...his office is calling me to see if I've gotten one, should I get an MRI? Is it needed? Are they noisy?
They are loud, but hearing protection helps. One of the MRI facilities gave me earplugs, then foam adhesive earmuffs (which they usually use as ear protection for children), and then large foam pads were secured around my head and jaw. I could barely hear anything. The techs had to yell to communicate with me.
One other thing, it's not the same constant noise the entire time. There are moments of quiet as the machine adjusts and different sounds based on the scan settings. Also, the MRI machines vary in volume based on manufacturer.
