I have ms, what does few scattered foci of increased t2 signal intensity in the white matter mean from an mri report mean?

Confirmation: If you have confirmed MS from other tests like a lumbar puncture and characteristic changes in your CSF, as well as clinical history that supports the diagnosis, then the foci of increased T2 intensity in the white matter may just be the areas in your brain that are being affected by the MS. Keeping track of these and their progression can help determine the progression of your disease.

MRI: Sorry to hear that, hope you have the mild form. It means that your immune system has attacked the protective sheath (myelin) that covers your nerves and has destroyed them. This could disrupt the communication between your brain and body parts.

Interpretation: Important that these films be compared with the prior studies. If done, then this means that you are acquiring more inflammatory lesions, and possibly your MS medication lacks sufficient potency to control progression. See your neurologist face-to-face and decide if you need to change your current treatment protocol.
