in an mra, a intrinsic scan ,detailed, is taken of your artery and the fill of blood in the
vessel, if any mentioned above would be the
culprit, it would appear. the
mri scan looks at the brain in detail, csf,sulcus, deviation any masses,changes,edema,fluid, old vs new cva, its amazingly detailed. if you had a mass,bleed, a developing aneurysm it would have picked it up. so iwouldnt worry about that.
