MRI scan with metal aortic valve

[MickP1000]

Has anyone with a recent metal replacement aortic valve had an MRI scan? I’m due my first annual scan post op. The surgeon said it would be a CT scan. The cardiologist wants to book me for an MRI saying it is simpler ( no constraints dye etc). I did challenge whether I could have one with a metal valve. He said it would be ok. Googling suggests it is with modern valves at a certain level but interested to see if anyone has had one without incident !

Hi MickP,

I had an MRI 8years ago following one of my surgeries.

AV and MV both Mech. I was recovering in hospital at the time, with all sorts of tests, so it didn't mean anything to me back then. As far as I know, I didn't have any problems from the MRI. Gold standard from what I can gather.

Thank you

It's worth double checking with the radiology dept. There will be a form you fill in (or equivalent) which asks if you have any metal implants. This might cause a hiatus. I have a cochlear implant and it's safe up to a certain MRI power. But some radiology depts simply say no because it's an implant.

Hi - this is food for thought: youtube.com/watch?v=IF6CMrj...(Not working as expected?)

There are other videos showing the strength of an MRI with metal. If it is just to make things easier for them, then I would not accept that and prefer a CT scan - especially if the original surgeon who placed the valve said CT scan. It is fine for you to request what is rightfully yours. The magnetic strength of MRI's is unbelievable!

When I had a new AV I got a card which states "MR conditional" and a warning MR in a triangle. It then gives maximum figures for Static Field, spatial gradient field, and whole body SAR (whatever that is). I assume these mean something to the radiologists.

As far as getting me into an MRI scanner, I have a real problem with claustrophobia, and they'd need to sedate me! I even get a touch in a CT scanner, if they raise the bed too high so my face is near the arch.

p.s., some MRIs can do "4D" scans, i.e. 3D mapping along a time line, and can see interesting flow patterns through the valve and in the aorta.
