Almost: A conventional cerebral angiogram is still considered the gold standard, but there is about a 1% chance of stroke from the procedure, plus other risks from needing to enter an artery. There is an advantage that if you have a treatable lesion, they can do a procedure during the angiogram. Otherwise, I almost always recommend the MR-angiogram or CT-angiogram because there is almost no risk.
