there are no silly questions here...we're all still learning!
No, MRI will not show the veins-
MRI will show lesion location, and spots of damage in the brain and spine. MRV is magnetic resonant venography, and as sou said, with DSV, or different forms of venography (depending on what you have access to), you can clearly see the architecture of the veins. It's good to have both done, so that neurologists and vascular doctors can see how the areas of venous blockage and lesions correspond.
Jeff had both done at Stanford, and they showed a direct correlation between the location of his cervical lesion and the area of jugular blockage on both sides of the lesion. His 20 brain lesions up stream also correspond to the pattern of reflux his jugular blockage caused in his brain.
In less than 2 months, he'll have both MRI and MRV redone. We'll see how things look then, and if there's been any change. Once we have any results- we'll let you know.
