On Oct 22nd, 2012 comparing this to a MRI I had in May 2011. I had MRI done with and without Contrast. In the past there were measurements of the lesions and they were all over my brain,and down my cervical spine. The two sentences that stood out were ...several of these lesions have retracted in volume since the  last study. there is no evidence of new mr white matter lesions . No definite poserior fossa lesions were identified. Thanks to Dr. Hernandez and his team the blood flow is definitely helping with the ms. I am on the mend. Close to eight months post jugular vein reconstruction. Yes it has taken time to heal from the surgery but life gets better every day.
