3T MRI?

[anon07072023]

Hi everyone, They're finally getting a 3T MRI in the city that I live.

However, I just found out that it's a 3T wide bore MRI.  Anyone know if that's the same as an open MRI?  If it is, then that not that great, because my previous neuro wouldn't allow any type of open MRIs for imaging because they're not clear enough.

It's supposed to be available sometime in mid Aug. and I'm do for more MRIs in the fall.

Thanks.
Kelly

Thank you both for your very detailed answers.  So, it looks like it's a go, then, since it's not open.  
Now the trick is to convince my neuro to let me have one at least on my spine, and then to convince Cigna to pay for it.  Since it's supposed to be much better, I'm sure that means it's more expensive.  

Mary, that's interesting what you brought up regarding the size of people and the size of the tube - how it could translate into better or worse images. I definitely want better.

Thanks!

An open MRI machine gets its name from the fact that it doesn't completely surround the person being imaged.  It is most likely a "C" shape.

Closed MRI machine results in better images because its tube shape allows the magnet to rotate completely around the person inside.  It can therefore collect more data from multiple angles to create clearer images and provide better information.  A closed MRI machine may be open on one or both ends.

A large bore machine is tube shaped but has a larger diameter so it can accommodate larger people.  I think the traditional closed MRI can only be used by people weighing less than about 300 pounds (or a bit below that).

Large bore machines are great for larger people who have been limited to open MR imaging in the past.  My guess is this hospital is purchasing the large bore MRI to expand imaging services to a greater number of consumers.  It makes sense to upgrade their tesla strength on new equipment at the time of purchase.  I doubt it makes economic sense to upgrade later (if it's even possible).  Besides, it gives them lots of improvement to advertise and health care is extremely commercial these days.  (It’s okay; it can work to our advantage.)

Kelly, I don't know if there is an image quality issue to consider with your shrinking size.  There are so many factors involved in imaging.  I remember hearing something in the past about person vs. tube size but I can't remember WHAT.  That part might be a good question to ask the radiology department at the hospital purchasing this nice new equipment.

The hospital where I receive most of my care has a service that allows people to email questions to specific departments about the services they provide.  They could probably tell you if a petite lady would be able to get good 3T MR images by using their new big boy machine.  I'd also ask them how long they expect the wait time to be from call date to test day when scheduling non-emergency cases.

I hope the timing of this is right for you and you are able to take advantage of this 3T imaging to find some of the answers you need!

What I found says that it is a closed machine:

3 Tesla Wide Bore MRI

    Our 3 Tesla Wide Bore MRI has the highest field strength clinically available ensuring quality images. The superior image quality helps physicians make a more precise diagnosis leading to a better treatment plan.

    If you are considering an "open" MRI scanner, you may want to reconsider. Our new extra spacious MRI offers better images and more room, so you can feel comfortable even if you’re claustrophobic. In fact, for many exams, your head stays outside of the machine.

    Be sure to let your physician know before scheduling your MRI if you are claustrophobic. Your physician can write you an order for the 3T Wide Bore MRI. You may also request it when you schedule.

    Our Wide Bore MRI Gives You:

        Two times higher quality images than the 1.5 MRI machines you will find at most surrounding facilities

        Four times higher quality images than open MRI machines

        The option to go in feet first for all scans

        A higher weight limit – up to 500 pounds

        A more comfortable table cushion

        More headroom, more legroom and more elbowroom

        Quick scanning of different areas without repositioning
