Hi. Thanks for your query.
Well I could have given you a more specific answer if you had given your clinical details of your problems.
Your report says, there are abnormal diffuse appearance of brain parenchyma in T1 and T2 weighted images and Incidental finding of a prominent perivascilar ? (Either periventricular or perivascular) spaces.
Now if the final report says, Normal MRI
of the brain, we would go by that for your age.
Incidental finding means, that it was not expected and it does not carry any significance if overall report is normal.
So, be reassured. If you are still concerned, mail me the MRI images with your clincal details; I shall help you further.
