VA occlusion: Small. If it were occluded, beyond the occlusion it would be absent. One VA is usually larger than the other; usually the left is larger but can be the right. Why didn't you ask this question of the doctor who ordered the MRA? THAT doctor is ethically obligated to interpret test results for you, or if unable, to find someone who can. Remember: The MRA isn't the patient; YOU are.
