Clear MRI

My last 2 MRI's (my last one was in 2022) were clean as in no lesions, just some grey matter but no lesions at all. I've had 3 spinal taps since 2015 (all positive) and the gamut of MS symptoms (that are progressing). I can't remember if the MS center back in 2016 diagnosed me with MS due to positive spinal taps and my symptoms/history or if they saw any lesions. Has anyone else had a clean/clear MRI but have been diagnosed with MS? Dr. Google said it is possible, but rare to have MS without lesions IF you have a positive spinal tap, symptoms/history and everything else has been ruled out (in my case they went A-Z to rule everything else out). I'm just wondering if I'm THAT RARE.
