I just got my MRI results back and it says that T1 AND T2 weighted images of the brain demonstrate an abnormal diffuse appearance of the brain parenchyma. Incidentally noted are prominent perivascilar spaces....what does this mean? But it sayd Normal mri of the brain for my age....I m 33
Hi,T1 and T2 weighted images are the sequences of MRI done in order to differentiate between gray and white matter of brain. Usually there will be demarcation seen between white matter and gray matter of brain parenchymal. Abnormal diffuse appearance can be early feature of cerebral edema. If you are not symptomatic (headache, vomiting, visual osculation)you need not worry. This abnormal diffuse appearance can also be artifacts of MRI. Prominent perivascular spaces are spaces around blood vessel which is also normal in your case.
