Eli,This is a good thing to have your test scheduled sooner rather than later.
You will have all of us tag-a-longs on your shoulder as you head back for more tests. You will be taking all of your fan club along with you on your shoulder.
Magnetic resonance arteriography illustrates the circle of Willis and its branches. The circle of Willis sits at the base of the brain. Your test will provide more information for the Drs. as well as documenting how things appear at this time. The CW is considered an important collateral pathway in maintaining adequate cerebral blood flow so taking a peek at your vessels in this area is just a good practice in helping your Dr. in learning more re why you have experienced 2 small strokes in the past.
The last time I had a CT of my head ( January of 2013) the report read " normal for age" - What - hey Doc, you can tell me I am normal but not as normal as I would have been 20 years ago???
My prayers go with you for the best outcome and soon all the testing will be yesterdays news.
