Where can I get an MRI without a prescription?

So I have gym injuries in my knees and shoulders. Want to get MRIs for them, but when I asked my doctor, he just dismissed my concerns and said it's not needed. I still wanna get it done because I won't be at peace until I can actually see what damage has actually been done. So is there any good and reliable place in Thane where I can get an MRI done? Especially without any doctor's note/prescription Also, does it matter where I get the MRI from? If I ever need to take my MRI report to a doctor, will it matter where I have gotten it done from ?
