Like the other answerer, I'm not sure where "T2 signals" come from, but I do understand MS lesions.
In MS, a person's own body - white blood cells - attack and destroy the mylin sheath of the body's nerve system. Enough demylination and that "site" will show up as a lesion - white - in an MRI.
If you go to any search engine and plug in the terms Multiple Sclerosis lesions you can get more info, and probably some pictures. Plug in T2 signals also and see what you get.
Good luck!!

The final reply was once proper. For MS, the sufferer is injected with Gadolinium, and a T2-weighted MRI sequence is administered. This suggests "lively" lesions, or lesions where damaging pastime is presently ongoing. Coupled with the complete quantity of lesions, this offers a sign of the development of the disorder.

I'm not sure what T2 signals are, but I think lesions are the areas of your brain affected or damaged by the symptoms of MS. They are the white spots on your brain found when an MRI is taken. I was just diagnosed with MS a month ago.

For MS, the patient is injected with Gadolinium, and a T2-weighted MRI series is run. This indicates "active" lesions, or lesions in which destructive activity is currently ongoing. Coupled with the total number of lesions (shown in a T1-weighted series before Gd is injected), this gives an indication of the advancement of the disease.
