I had a 20 minute MRI today on my knee.
I've been really worried about having a loud MRI, and I spent ages researching a private hospital with latest software silent scan MRI technology so I wouldn't make my tinnitus worse.
I spoke to the radiologist before several times, who advised me that their silent MRI would only be 6 dB above ambient noise levels, and it used a mixture of two scan technologies - GE Silent Scan (and the even quieter Silenz scan). He even downloaded a new software and ran a sequence on the machine one day with nobody in it just to test it for me! He went in the MRI room himself and said that it was only just audible above the ambient room noise.
This made me very confident. Then I had the scan...
