I have been feeling vetigo. I am in good health, no blood pressure, or weight issues, only underactive thyroid. I am a active senior female of 65. I had a MRI/MRA of the neck and brain done w/o contrast. For the neck- There is a quesion of stenosis near the the origin of the left common carotid artery vertebral artery. Dr suggested CT angiogram for confirmation. I am wondering if there are other methods to angiogram?
