A 41-year-old member asked:

which test is more conclusive: an mra of the brain or an angiogram?

Brain angio: An MRA of the brain is very robust. With MR you can have a 3-dimensional picture of the vascular anatomy. MR does not have any radiation, the contrast less commonly has adverse reaction and is noninvasive. The only compelling reason not to do MR is if you have other contraindications or need actual intervention (ex. embolization)

Possible allergy: While generally safe, this procedure can be complicated by allergy to the contrast embolus causing a stroke dissection of the artery causing a stroke perforation of a vessel causing bleeding at the site of the insertion of the catheter or more distally damage to the vessel at site of insertion of the catheter requiring surgical repair.

Vascular anatomy: Angiograms are the gold standard for defining the vascular anatomy of the brain, but i can't tell you why you need one. They will demonstrate intracranial atherosclerosis, aneurysms, feeding and draining vessels to an arteriovenous malformation, vascular feeding vessels to a tumor, vascular steal phenomemon and many other processes. When the dye is injected, you may get a warm sensation.
A 21-year-old female asked:

How long do I have to remain still after a brain angiogram?

1 doctor answer1 doctor weighed in
Dr. Andrew Dutka
Neurology 45 years experience
Hours: You have to remain still to avoid bleeding at the site of the puncture for the catheter. If it is in the groin, the doctors may have used an artery closure device, and you can move after 3 hours. If they did not use a closure device, six hours is better.
