Well, that had to be frustrating, ! I did some digging and frankly, I got completely mixed answers on the braces issue in regards to MRIs. While every reputable source I checked stated that it was safe to get an MRI with braces, whether or not the small amount of metal will affect MRI results seems up for debate. Did the tech suggest your braces may have caused the distorted pictures?
Have you had other tests done? I only ask because there are a number of tests a physician will use to diagnose MS. You can read about those tests here -- https://multiplesclerosis.net/diagnosis/tools-your-doctor-will-use-to-make-a-diagnosis. An MRI is an important diagnostic tool, but a diagnosis can be achieved with other tests, if necessary. A CT scan *could* be helpful, but I would definitely discuss that with your doctor. It's really going to be a decision you and your doctor make.
I know that's probably not the answer you were looking for, but you have to find out what works best for you, considering your symptoms, your tolerance for tests, and, possibly, (if you're in the USA) your insurance coverage.
