How to Get the Quietest MRI Experience?

[Gecko]

Hi Gecko,

I posted last month asking same question but didn't hear anything.

Canon supposedly has great machines but they will not give out details where they exists for liability reasons. Which seams so counterintuitive.

After doing a ton of research I contacted G.E. directly as they also have machines that can run considerably quieter sequences. They put me in touch with Newport diagnostics here in Southern California. There they had a machine that could run in quieter modes. It was much easier. There was only a few sequences where it had to be run a little loud but it was completely tolerable with earplugs and only for 2 minutes tops. I would say that I have pretty off the charts reactive tinnitus and I walked out of it completely unscathed. You will still have to wear earplugs, as it will be about half as loud as a normal MRI but nowhere near the volume or intensity.

Thanks so much, Alan P, for the helpful information!

So I had 2 additional MRI exams last week.

1st one on Monday (coccyx) then a 2nd one on Friday (thoracic spine). Both on the latest Canon Orian 1.5T.

Both with EarSoft FX earplugs carefully deeply inserted + MRI approved earmuffs. 1st one with the head slightly outside the MRI tunnel, 2nd one with the head right in the middle of the tunnel. Both around 15-20 minutes long.

Like with the 1st one a year ago, I hummed/whispered a melody during the various sequences in order to cover the noise of the machine and relax (since with earplugs, it resonates in your head, so only a whisper is enough). It worked great again. Some sequences are louder and/or longer than others and are still stressful, clear, but I think it is more due to the anxiety and the negative emotion you put behind the context/type of noise than really the noise level itself.

It was obviously not pleasant, but both MRI exams were fine. No spike or any effect on my tinnitus or hyperacusis.

So I have been through 3 MRI exams in 1 year. All with Canon Orian and I am now sure MRI exams on that machine are no problem for me.

I have noise induced tinnitus + mild hyperacusis but I used to have quite severe hyperacusis a few years ago.

BTW I discussed a long moment with the MRI operator. He is also working on a GE MRI at the local hospital nearby and he confirmed the GE are WAY louder.

He told me he has worked over the last 10 years on every MRI brand (GE, Siemens, Canon) and the Canon are by far the quietest (and GE the worst in terms of noise). On the Canon Orian he usually does not supply any ear protection to the patients. By the way Canon Medical is apparently no longer supplying earmuffs with the machine since the average sound pressure/level is probably below the regulatory limit. On the GE it is not allowed and he would anyhow NEVER do an MRI exam without giving ear protection to the patient.

He added that even for them, as operators, it is much more comfortable to work on Canon because it is much more quiet behind the glass wall.

All in all, it confirmed to me that everytime I need an MRI I should go for the Canon, which is btw already exactly what I am doing.

So no surprise here.

Take care.

Just curious, what was the dB level?

 

[Baker]

Does anyone have a list of MRI machines that are ordered from the quietest to the loudest? It seems the information is all over the place. And from what I'm reading here, the Canon are the quietest? Are there some Canon models more quieter than others?

And does anyone know of one in Tennessee, USA?

Thanks.

 

[Brian P]

Just use double protection if you really need an MRI.

 

[Baker]

I'm going to take every precaution necessary as I would be in the MRI machine for an hour.

I'm going to try and find out what MRI machines are the quietest and see if there is one in driving distance. I believe from what I've read that the Canon MRI machines are supposed to be the quietest? Are there certain models that are quieter than others?

My research says Canon Vantage machines with Pianissimo hardware noise reduction technology (magnets in vacuum chambers) are the quietest. I don't know if any of the many models is quieter than the others.

Thanks. Is there an easy way to find out what places have these machines? It seems like finding this info is really hard. I guess some people have had luck. I did contact Canon a while back who told me they don't give out that information.

Here is a pdf listing of all the MRI machines in Tennessee.

https://www.tn.gov/content/dam/tn/hsda/documents/mri-equipment-listing.pdf

Look for Canon or Toshiba models, I see a handful of them. There are multiple Vantage models that can have Pianissimo hardware noise reduction technology where the magnets are enclosed in vacuum chambers to reduce sound transmission. Examples are Fortian, Galan, Elan, Titan and Orion. There is also Pianissimo software technology which further reduces noise on certain sequences but I would make sure that the machine has the hardware option.

Please report back on what you learn and experience if you get the scan.

Good luck,


George

Thanks. I never knew something like that existed.

How can one found out if a certain State has this information? I'm not sure how one would search for this on a State website other than trying random Google searches?

I'm going to have to do more research on Toshiba vs Canon. Though it looks like from a quick search that maybe these quiet MRI machines started with Toshiba and that they changed their name to Canon?

The Toshiba line of MRI machines were bought by Canon so they are one and the same. I just searched Canon Toshiba MRI Vantage Tennessee and plowed through a dozen search returns to find that chart.

I saw a handful of options for you in that chart. Florida where I am from has no such chart that I can find. I only have one in the state of Florida that I have been able to locate.

I looked through some old notes and found that I wrote that the Canon Vantage Galan 3T is "20% quieter".

Now I don't know what that is in comparison to as in 20% quieter than a standard MRI machine or if it's 20% quieter compared to other Canon Vantage MRI machines. I think I might have gotten that info from Tinnitus Talk, though not sure.

Also, I've read that the 3T MRI machines don't just give you a more detailed image, but I believe the scan time is supposed to be faster than compared to a 1.5T MRI machine.

I'm going to try and see if I can find what MRI machines the neighboring states have. Also, I'll have to see if I can contact the person or whoever at Canon I've read about here to see if he has a list of what Canon MRI machines they have in nearby regions.

I went through the list that I sent you and there are 9 Toshiba/Canon MRI machines listed in Tennessee and a few of them even give the exact names that we should be looking for such as Canon Vantage Titan. Were all 9 of these listings a bust? I doubt that any state will have a better selection resource than Tennessee does, this should make it very easy for you to find one of the lowest loudness choices.

George

 

[GlennS]

Someone should really compile a state-by-state database somehow of recommended MRI locations. I damaged my wrist at the end of August and I really should get an MRI because it's not really getting better and X-rays did not reveal the root problem.

I've not had time to check any of those places out yet as I'm chronically ill and am chronically tired (Lyme Disease), but from reading my notes I had been looking at a Vantage Galan 3T as it's supposed to be quieter and shorter duration than the 1.5T models? And I believe it's supposed to be a short bore, which would work better if you have claustrophobia. As I have to be very careful as my tinnitus will get permanently worse even just being exposed to brief loud noises like a drill without wearing hearing protection, etc. It'll even get worse if I accidentally smack my ear. It's scary being in town and some guy blows past you in what sounds like a very loud race car, or an ambulance comes blasting by. I have to plug my ears with my fingers.

I'm hoping a 3T machine would give better detail than a 1.5T machine at showing a spinal cord injury (self-diagnosed) i.e. a reduction in signal or not, so maybe I can get correctly diagnosed and prove that I'm partially paralyzed. Also, I'll be needing to get my whole spine done, and so a 3T being a shorter duration would probably be better as that scan can easily take an hour. Hopefully I can find one within driving distance as I don't have the funds (on disability) to fly to a place. Am trying to do a telehealth appointment with the Mayo Clinic spine center, and so I'll ask if they have a list of places that have the quiet Vantage series including the Galan 3T.

 

[GeorgeLG]

@Baker, in one study, 1.5T machines are 18 - 25 dB quieter (depending on the sequence) than 3T machine which is a huge difference as the decibel scale is not linear - a 4X difference in perceived loudness in this case. This data is not Canon or Toshiba specific.

I have no idea what resources other states provide with regards to listing all of the MRI machines in their state but given your limitations the fact that your state offers a detailed roadmap, you hit the jackpot. My state (Florida) has no such resource or at least not findable on the interweb and I can find almost anything.

In the summary of the report:

"The gradient noise level from a 3T MR scanner exceeded the regulatory limit of the equivalent noise level of 99 dB in all pulse sequences. Therefore, the use of proper ear protection devices is essential. Our subjective noise evaluation revealed that the simultaneous use of both earplugs and headphones is recommended during 3T use."

I've spent about 2.5 hours total in a Canon Vantage Galan 3T for brain + full spine scans. It has had zero impact on my tinnitus. A couple key things though.

The first - be sure you get an MRI on a Canon machine that has the Pianissimo technology.

The second - learn how to put ear plugs in properly, and practice it beforehand. Bring your own plugs that are rated 33NRR. I've been using Hearos. With my earplugs properly inserted, the noise was very tolerable. I perceived it as quieter than my car ride to get to the hospital even.

What the MRIs found is a lot scarier than tinnitus though

 

[GeorgeLG]

Like the entire tinnitus subject, we are all different and there is no way to know how this will affect any one of us in particular until we do it. The way I see it is that we should at least lower the odds of any permanent damage if a lower noise option is available to us or avoid these scans altogether if not absolutely necessary. I am also talking with my doctor about whether a CT scan can get them what they need.

Just learnt from my rheumatologist yesterday that I have to do another MRI, this time for the cervical spine...

It will be the 4th in a bit more than one year

The 4th in a Canon Orian 1.5T...

The MRI center had a free slot tomorrow so no time to think too much...

But I am now much less anxious than before since I know where to go and that my ears will be fine.

If you don't mind, could you ask them if they are aware of what Canon MRI machines are the quietest? As I know Canon has different models and I can't really find information as to what the differences are as far as the sound level goes. Thanks!

They won't know.

People at the MRI center have no clue about the various noise levels within the Canon range.

As they are also using a GE MRI, they were just able to confirm the Canon is far quieter.

But frankly speaking, I think the noise level of the various Canon 1.5T currently in the range will be the same as they are using same hardware technology (vacuum) and same software technology (Pianissimo Zen).

The Local Director for Canon MRI confirmed to me in the past that The Canon Orian has similar noise level as former Toshiba Vantage Titan for example.

As regards the 3T, there are not many in France but from what I know, higher power often means higher noise level.

Finally I am a bit more anxious than expected as I have just realized that I won't be able to wear my usual earmuffs on top of my earplugs.

The 3 previous MRI I always used double protection: Earsoft FX earplugs + special MRI earmuffs.

But for the cervical MRI they will use another antenna... like the brain MRI headset probably and I won't be able to use my earmuffs... it sucks!

Hopefully the foam inside the head antenna will play a similar role as my earmuffs and in combination with my earplugs I will be fine...

How loud is the Siemens Skyra 3T MRI?

I can't find any info about this specific model here. I have an ankle injury that's been going on for 7 months and keeping me from walking. The doctor wants me to have an MRI. How loud is the Skyra 3T? I'm very scared. I don't want to live with worse tinnitus and being unable to walk. I have not slept in weeks.

I was not able to, but I asked multiple times and scheduled and canceled and rescheduled (until the receptionists were annoyed by me) about the quietest model. They told me the Skyra 3T had a "quiet suite" which could make it just slightly lower but longer. The MRI tech wanted to make sure I knew that it would still be loud. I see many people here have had a severe increase even with the "quiet suite." I tried to find Canon and Toshiba models in my area but they were not within 100 miles of me. I live in New York.
