Hey, me too.
(not my fault. Cletus made me)
I have an artificial knee and an artificial ankle. And I recently underwent an mri on my good knee. Only metals that can be magnetized are affected by mri. I dont think any are used in implants.

I have a LINX implant. I ring of metallic balls that goes around the esophagus. Fixes hiatel hernias. I can get MRIs as long as they aren’t on the newest high powered machines. I can’t remember if that is T3? I have it on a card in my wallet.
Should have read “ring of magnetized metallic balls”.

Newer implants have taken MRI into account whereas older implants didn’t as the tech just came out in the 80s for the most part. However there are still a lot of stainless steel implants that can create issues at higher field strengths from heating if not magnetic pull. Heck Tatoo ink can cause issues at the higher field strengths.
3 Tesla (T) magnets are becoming the go to standard due to the better resolution. Old er models under 1 Tesla aren’t even really being considered standard care any longer and those were made as late as 2005 when I left the MR system plant to move onto other activities. I think there may still be some open sided magnets being used for claustrophobic patients but that is about it and they ran up to around 0.7T.
