I live with seniors, lots of them. Amongst us we have had at least 30 hip replacements and revisions, and only one had an MRI, but her femur was shattered in an accident prior to surgery.
So I would say the standard of car does not include an MRI. The problems with my hips were very clear on x-rays.

I have had hip surgery on both my hips. I had MRI's on both. You can't tell what is going on with the muscles if you don't have an MRI. I would never accept a doctor that wouldn't do an MRI first. One hip was done in 2019 and the other in 2020.

I have had both RTS and TKR had all kinds of MRI S with and without contrast for regular surgery and in my experience even with mris you never get the full picture until a surgeon opens u up for surgery. Same true had mri from primary care doc first as pt sent me back when not making progress then had a total RTS. For my knee I asked surgeon if he needed to do an mri for the TKR. He said no he could see everything he needed to see on the X-ray to know I needed a new knee. Hope that helps.
I am assuming your doc sees what he needs to see on X-ray my new knee is awesome had it done 11 months ago. Surgeon told me RTS was most difficult the TKR is second with Hip being easiest to get through. Good luck most importantly find a good physical therapist that is just as important as finding a good surgeon! It’s work on our part too! Lots! Good luck
